TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 13 of 97 11.05.2005 Requirements of quality IEC 60068 Environmental testing DIN EN 60529 IP codes Compliance with international rules and regulations Manufacturers of mobile or fixed devices incorporating TC63 modules are advised to have their completed product tested and approved for compliance with all applicable national and international regulations. As a quad-band GSM/GPRS engine designed for use on any GSM network in the world, TC63 is required to pass all approvals relevant to operation on the European and North American markets. For the North American market this includes the Rules and Regulations of the Federal Communications Commission (FCC) and PTCRB, for the European market the R&TTE Directives and GCF Certification Criteria must be fully satisfied. The FCC Equipment Authorization granted to the TC63 Siemens reference application is valid only for the equipment described in Section 8.1. SAR requirements specific to portable mobiles Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM module must be in accordance with the guidelines for human exposure to radio frequency energy. This requires the Specific Absorption Rate (SAR) of portable TC63 based applications to be evaluated and approved for compliance with national and/or international regulations. Since the SAR value varies significantly with the individual product design manufacturers are advised to submit their product for approval if designed for portable use. For European and US markets the relevant directives are mentioned below. It is the responsibility of the manufacturer of the final product to verify whether or not further standards, recommendations or directives are in force outside these areas. Products intended for sale on US markets ES 59005/ANSI C95.1 Considerations for evaluation of human exposure to Electromagnetic Fields (EMFs) from Mobile Telecommunication Equipment (MTE) in the frequency range 30MHz - 6GHz Products intended for sale on European markets EN 50360 Product standard to demonstrate the compliance of mobile phones with the basic restrictions related to human exposure to electromagnetic fields (300MHz - 3GHz) Note: Usage of TC63 in a fixed, mobile or portable application is not allowed without a new FCC certification.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 14 of 97 11.05.2005 1.4 Safety Precautions The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating TC63. Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Siemens AG assumes no liability for customer’s failure to comply with these precautions. When in a hospital or other health care facility, observe the restrictions on the use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger. Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile, park the vehicle. Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 15 of 97 11.05.2005 SOS IMPORTANT! Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls. Remember, in order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call. Some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.

TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 22 of 97 11.05.2005 3.1 Operating Modes The table below briefly summarizes the various operating modes referred to in the following chapters. Table 1: Overview of operating modes GSM / GPRS SLEEP Various power save modes set with AT+CFUN command. Software is active to minimum extent. If the module was registered to the GSM network in IDLE mode, it is registered and paging with the BTS in SLEEP mode, too. Power saving can be chosen at different levels: The NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes AT+CFUN=7 and 9 alternatively activate and deactivate the AT interfaces to allow permanent access to all AT commands. GSM IDLE Software is active. Once registered to the GSM network, paging with BTS is carried out. The module is ready to send and receive. GSM TALK Connection between two subscribers is in progress. Power consumption depends on network coverage individual settings, such as DTX off/on, FR/EFR/HR, hopping sequences, antenna. GPRS IDLE Module is ready for GPRS data transfer, but no data is currently sent or received. Power consumption depends on network settings and GPRS configuration (e.g. multislot settings). Normal operation GPRS DATA GPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink / downlink data rates, GPRS configuration (e.g. used multislot settings) and reduction of maximum output power. POWER DOWN Normal shutdown after sending the AT^SMSO command. The Power Supply disconnects the supply voltage from the baseband part of the circuit. Only a voltage regulator is active for powering the RTC. Software is not active. Interfaces are not accessible. Operating voltage (connected to BATT+) remains applied.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 23 of 97 11.05.2005 Airplane mode Airplane mode shuts down the radio part of the module, causes the module to log off from the GSM/GPRS network and disables all AT commands whose execution requires a radio connection. Airplane mode can be controlled by using the AT commands AT^SCFG and AT+CALA: • With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured to enter the Airplane mode each time when switched on or reset. • The parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth between Normal mode and Airplane mode any time during operation. • Setting an alarm time with AT+CALA followed by AT^SMSO wakes the module up into Airplane mode at the scheduled time. Charge-only mode Limited operation for battery powered applications. Enables charging while module is detached from GSM network. Limited number of AT commands is accessible. Charge-only mode applies when the charger is connected if the module was powered down with AT^SMSO. Charge mode during normal operation Normal operation (SLEEP, IDLE, TALK, GPRS IDLE, GPRS DATA) and charging running in parallel. Charge mode changes to Charge-only mode when the module is powered down before charging has been completed. See Table 6 for the various options proceeding from one mode to another.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 24 of 97 11.05.2005 3.2 Power Supply TC63 needs to be connected to a power supply at the B2B connector (5 pins each BATT+ and GND). The power supply of TC63 has to be a single voltage source at BATT+. It must be able to provide the peak current during the uplink transmission. All the key functions for supplying power to the device are handled by the power management section of the analog controller. This IC provides the following features: • Stabilizes the supply voltages for the GSM baseband using low drop linear voltage regulators. • Switches the module's power voltages for the power up and down procedures. • Delivers, across the VEXT pin, a regulated voltage for an external application. This voltage is not available in Power-down mode. • SIM switch to provide SIM power supply. 3.2.1 Minimizing Power Losses When designing the power supply for your application please pay specific attention to power losses. Ensure that the input voltage VBATT+ never drops below 3.2V on the TC63 board, not even in a transmit burst where current consumption can rise to typical peaks of 2A. It should be noted that TC63 switches off when exceeding these limits. Any voltage drops that may occur in a transmit burst should not exceed 400mV. The measurement network monitors outburst and inburst values. The drop is the difference of both values. The maximum drop (Dmax) since the last start of the module will be saved. In IDLE and SLEEP mode, the module switches off if the minimum battery voltage (Vbattmin) is reached. Example: VImin = 3.2V Dmax = 0.35V Vbattmin = VImin + Dmax Vbattmin = 3.2V + 0.35V = 3.55V The best approach to reducing voltage drops is to use a board-to-board connection as recommended, and a low impedance power source. The resistance of the power supply lines on the host board and of a battery pack should also be considered. Note: If the application design requires an adapter cable between both board-to-board connectors, use a flex cable as short as possible in order to minimize power losses.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 25 of 97 11.05.2005 Example: If the length of the flex cable reaches the maximum length of 100mm, this connection may cause, for example, a resistance of 30m in the BATT+ line and 30m in the GND line. As a result, a 2A transmit burst would add up to a total voltage drop of 120mV. Plus, if a battery pack is involved, further losses may occur due to the resistance across the battery lines and the internal resistance of the battery including its protection circuit. Figure 3: Power supply limits during transmit burst 3.2.2 Measuring the Supply Voltage VBATT+ The reference points for measuring the supply voltage VBATT+ on the module are BATT+ and GND, both accessible at a capacitor located close to the board-to-board connector of the module. Figure 4: Position of the reference points BATT+ and GND 3.2.3 Monitoring Power Supply by AT Command To monitor the supply voltage you can also use the AT^SBV command which returns the value related to the reference points BATT+ and GND. The module continuously measures the voltage at intervals depending on the operating mode of the RF interface. The duration of measuring ranges from 0.5s in TALK/DATA mode to 50s when TC63 is in IDLE mode or Limited Service (deregistered). The displayed voltage (in mV) is averaged over the last measuring period before the AT^SBV command was executed.

TC63 would immediately switch off after having started and detected these inappropriate conditions. In extreme cases this can cause permanent damage to the module. 3.3.1 Turn on TC63 TC63 can be started in a variety of ways as described in the following sections: • Hardware driven start-up by IGT line: starts Normal mode or Airplane mode (see Section 3.3.1.1) • Software controlled reset by AT+CFUN command: starts Normal or Airplane mode (see Section 3.3.1.3) • Hardware driven start-up by VCHARGE line: starts charging algorithm and Charge-only mode (see Section 3.3.1.2) • Wake-up from Power-down mode by using RTC interrupt: starts Airplane mode The option whether to start into Normal mode or Airplane mode depends on the settings made with the AT^SCFG command or AT+CALA. With AT+CALA, followed by AT^SMSO the module can be configured to restart into Airplane mode at a scheduled alarm time. Switching back and forth between Normal mode and Airplane mode is possible any time during operation by using the AT^SCFG command. After startup or mode change the following URCs indicate the module’s ready state: • “SYSSTART” indicates that the module has entered Normal mode. • “^SYSSTART AIRPLANE MODE” indicates that the module has entered Airplane mode. • “^SYSSTART CHARGE ONLY MODE” indicates that the module has entered the Charge-only mode. Detailed explanations on AT^SCFG, AT+CFUN, AT+CALA and Airplane mode can be found in [1]. 3.3.1.1 Turn on TC63 Using Ignition Line IGT When the TC63 module is in Power-down mode, it can be started to Normal mode or Airplane mode by driving the IGT (ignition) line to ground. This must be accomplished with an open drain/collector driver to avoid current flowing into this pin. The module will start up when both of the following two conditions are met: • The supply voltage applied at BATT+ must be in the operating range. • The IGT line needs to be driven low for at least 400ms. Considering different strategies of host application design the figures below show two approaches to meet this requirement: The example in Figure 5 assumes that IGT is activated after BATT+ has already been applied. The example in Figure 6 assumes that IGT is held low before BATT+ is switched on. In either case, to power on the module, ensure that low state of IGT takes at least 400ms from the moment the voltage at BATT+ is available.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 27 of 97 11.05.2005 If configured to a fix baud rate (AT+IPR0), the module will send the URC “^SYSSTART” or “^SYSSTART AIRPLANE MODE” to notify that it is ready to operate.

If the charger is connected to the charger input of the external charging circuit and the module’s VCHARGE pin while TC63 is off, and the battery voltage is above the undervoltage lockout threshold, processor controlled fast charging starts (see Section 3.5.6). TC63 enters a restricted mode, referred to as Charge-only mode where only the charging algorithm will be launched. During the Charge-only mode TC63 is neither logged on to the GSM network nor are the serial interfaces fully accessible. To switch to normal operation and log on to the GSM network, the IGT line needs to be activated as described in Section 3.3.1.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 29 of 97 11.05.2005 3.3.1.3 Reset TC63 via AT+CFUN Command To reset and restart the TC63 module use the command AT+CFUN. You can enter AT+CFUN=,1 or AT+CFUN=x,1, where x may be in the range from 0 to 9. See [1] for details. If configured to a fix baud rate (AT+IPR0), the module will send the URC “^SYSSTART” or “^SYSSTART AIRPLANE MODE to notify that it is ready to operate. If autobauding is enabled (AT+IPR=0) there will be no notification. To register to the network SIM PIN authentication is necessary after restart. 3.3.1.4 Reset or Turn off TC63 in Case of Emergency Caution: Use the EMERG_RST pin only when, due to serious problems, the software is not responding for more than 5 seconds. Pulling the EMERG_RST pin causes the loss of all information stored in the volatile memory. Therefore, this procedure is intended only for use in case of emergency, e.g. if TC63 does not respond, if reset or shutdown via AT command fails. The EMERG_RST signal is available on the application interface. To control the EMERG_RST line it is recommended to use an open drain / collector driver. The EMERG_RST line can be used to switch off or to reset the module. In any case the EMERG_RST line must be pulled to ground for ≥10ms. Then, after releasing the EMERG_RST line additional activation of IGT for 400 ms will reset the module. If IGT is not activated for 400 ms the module switches off. In this case, it can be restarted any time as described in section 3.3.1.1. After hardware driven restart, notification via “^SYSSTART” or “^SYSSTART AIRPLANE” URC is the same as in case of restart by IGT or AT command. To register to the network SIM PIN authentication is necessary after restart.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 30 of 97 11.05.2005 3.3.2 Turn off TC63 TC63 can be turned off as follows: • Normal shutdown: Software controlled by AT^SMSO command • Automatic shutdown: Takes effect if board or battery temperature is out of range or if undervoltage or overvoltage conditions occur. 3.3.2.1 Turn off TC63 Using AT Command The best and safest approach to powering down TC63 is to issue the AT^SMSO command. This procedure lets TC63 log off from the network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to as Power-down mode. In this mode, only the RTC stays active. Before switching off the device sends the following response: ^SMSO: MS OFF OK ^SHUTDOWN After sending AT^SMSO do not enter any other AT commands. There are two ways to verify when the module turns off: • Wait for the URC “^SHUTDOWN”. It indicates that data have been stored non-volatile and the module turns off in less than 1 second. • Also, you can monitor the PWR_IND pin. High state of PWR_IND definitely indicates that the module is switched off. Be sure not to disconnect the supply voltage VBATT+ before the URC “^SHUTDOWN” has been issued and the PWR_IND signal has gone high. Otherwise you run the risk of losing data. Signal states during turn-off are shown in Figure 7. While TC63 is in Power-down mode the application interface is switched off and must not be fed from any other source. Therefore, your application must be designed to avoid any current flow into any digital pins of the application interface, especially of the serial interfaces. No special care is required for the USB interface which is protected from reverse current.

Therefore, in order to minimize the leakage current take care to start up the module at least once before it is powered down.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 32 of 97 11.05.2005 3.3.3 Automatic Shutdown Automatic shutdown takes effect if • the TC63 board is exceeding the critical limits of overtemperature or undertemperature • the battery is exceeding the critical limits of overtemperature or undertemperature • undervoltage or overvoltage is detected See Charge-only mode described in section 3.5.7 for exceptions. The automatic shutdown procedure is equivalent to the Power-down initiated with the AT^SMSO command, i.e. TC63 logs off from the network and the software enters a secure state avoiding loss of data. Alert messages transmitted before the device switches off are implemented as Unsolicited Result Codes (URCs). The presentation of these URCs can be enabled or disabled with the two AT commands AT^SBC and AT^SCTM. The URC presentation mode varies with the condition, please see Chapters 3.3.3.1 to 3.3.3.4 for details. For further instructions on AT commands refer to [1]. 3.3.3.1 Temperature Dependent Shutdown The board temperature is constantly monitored by an internal NTC resistor located on the PCB. The NTC that detects the battery temperature must be part of the battery pack circuit as described in 3.5.3 The values detected by either NTC resistor are measured directly on the board or the battery and therefore, are not fully identical with the ambient temperature. Each time the board or battery temperature goes out of range or back to normal, TC63 instantly displays an alert (if enabled). • URCs indicating the level "1" or "-1" allow the user to take appropriate precautions, such as protecting the module from exposure to extreme conditions. The presentation of the URCs depends on the settings selected with the AT^SCTM write command: AT^SCTM=1: Presentation of URCs is always enabled. AT^SCTM=0 (default): Presentation of URCs is enabled for 15 seconds time after start-up of TC63. After 15 seconds operation, the presentation will be disabled, i.e. no alert messages can be generated. • URCs indicating the level "2" or "-2" are instantly followed by an orderly shutdown. The presentation of these URCs is always enabled, i.e. they will be output even though the factory setting AT^SCTM=0 was never changed. The maximum temperature ratings are stated in Table 16. Refer to Table 2 for the associated URCs. All statements are based on test conditions according to IEC 60068-2-2 (still air).

TC63 switches off. ^SCTM_B: -2 Alert: Tamb of board equal or below undertemperature limit. TC63 switches off. 3.3.3.2 Temperature Control during Emergency call If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure the temperature, but deactivates the shutdown functionality. If the temperature is still out of range when the call ends, the module switches off immediately (without another alert message). 3.3.3.3 Undervoltage Shutdown if Battery NTC is Present In applications where the module’s charging technique is used and an NTC is connected to the BATT_TEMP terminal, the software constantly monitors the applied voltage. If the measured battery voltage is no more sufficient to set up a call the following URC will be presented: ^SBC: Undervoltage. The message will be reported, for example, when the user attempts to make a call while the voltage is close to the shutdown threshold of 3.2V and further power loss is caused during the transmit burst. In IDLE mode, the shutdown threshold is the sum of the module’s minimum supply voltage (3.2V) and the value of the maximum voltage drop resulting from earlier calls. This means that in IDLE mode the actual shutdown threshold may be higher than 3.2V. Therefore, to properly calculate the actual shutdown threshold application manufacturers are advised to measure the maximum voltage drops that may occur during transmit bursts. To remind the user that the battery needs to be charged soon, the URC appears several times before the module switches off. To enable or disable the URC use the AT^SBC command. The URC will be enabled when you enter the write command and specify the current consumption of your host application. Step by step instructions are provided in [1].
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 34 of 97 11.05.2005 3.3.3.4 Undervoltage Shutdown if no Battery NTC is Present The undervoltage protection is also effective in applications, where no NTC connects to the BATT_TEMP terminal. Thus, you can take advantage of this feature even though the application handles the charging process or TC63 is fed by a fixed supply voltage. All you need to do is executing the write command AT^SBC=<current> which automatically enables the presentation of URCs. You do not need to specify <current>. Whenever the supply voltage falls below the value of 3.2V the URC ^SBC: Undervoltage appears several times before the module switches off. 3.3.3.5 Overvoltage Shutdown The overvoltage shutdown threshold is 100mV above the maximum supply voltage VBATT+ specified in Table 18. When the supply voltage approaches the overvoltage shutdown threshold the module will send the following URC ^SBC: Overvoltage warning This alert is sent once. When the overvoltage shutdown threshold is exceeded the module will send the URC ^SBC: Overvoltage shutdown before it shuts down cleanly. Keep in mind that several TC63 components are directly linked to BATT+ and, therefore, the supply voltage remains applied at major parts of TC63, even if the module is switched off. Especially the power amplifier is very sensitive to high voltage and might even be destroyed.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 35 of 97 11.05.2005 3.4 Automatic GPRS Multislot Class Change Temperature control is also effective for operation in GPRS Multislot Class 10 and GPRS Multislot Class 12. If the board temperature increases to the limit specified for restricted operation1) while data are transmitted over GPRS, the module automatically reverts: • from GPRS Multislot Class 12 (4Tx slots) to GPRS Multislot Class 8 (1Tx) • from GPRS Multislot Class 10 (2Tx slots) to GPRS Multislot Class 8 (1Tx) This reduces the power consumption and, consequently, causes the board’s temperature to decrease. Once the temperature drops to a value of 5 degrees below the limit of restricted operation, TC63 returns to the higher Multislot Class. If the temperature stays at the critical level or even continues to rise, TC63 will not switch back to the higher class. After a transition from GPRS Multislot Class 12 or 10 to GPRS Multislot Class 8 a possible switchback to GPRS Multislot Class 12 or 10 is blocked for one minute. Please note that there is not one single cause of switching over to a lower Multislot Class. Rather it is the result of an interaction of several factors, such as the board temperature that depends largely on the ambient temperature, the operating mode and the transmit power. Furthermore, take into account that there is a delay until the network proceeds to a lower or, accordingly, higher Multislot Class. The delay time is network dependent. In extreme cases, if it takes too much time for the network and the temperature cannot drop due to this delay, the module may even switch off as described in Section 3.3.3.1. 1) See Table 16 for temperature limits known as restricted operation.

You can skip this chapter if charging is not your concern, or if you are not using the implemented charging algorithm. The following sections contain an overview of charging and battery specifications. Please refer to [4] for greater detail, especially regarding requirements for batteries and chargers, appropriate charging circuits, recommended batteries and an analysis of operational issues typical of battery powered GSM/GPRS applications. 3.5.1 Hardware Requirements TC63 has no on-board charging circuit. To benefit from the implemented charging management you are required to install a charging circuit within your application according to the Figure 38. 3.5.2 Software Requirements Use the command AT^SBC, parameter <current>, to enter the current consumption of the host application. This information enables the TC63 module to correctly determine the end of charging and terminate charging automatically when the battery is fully charged. If the <current> value is inaccurate and the application draws a current higher than the final charge current, either charging will not be terminated or the battery fails to reach its maximum voltage. Therefore, the termination condition is defined as: final charge current (50mA) plus current consumption of the external application. If used the current flowing over the VEXT pin of the application interface (typically 2.9V) must be added, too. The parameter <current> is volatile, meaning that the factory default (0mA) is restored each time the module is powered down or reset. Therefore, for better control of charging, it is recommended to enter the value every time the module is started. See [1] for details on AT^SBC. 3.5.3 Battery Pack Requirements The charging algorithm has been optimized for rechargeable Lithium batteries that meet the characteristics listed below and in Table 3. It is recommended that the battery pack you want to integrate into your TC63 application is compliant with these specifications. This ensures reliable operation, proper charging and, particularly, allows you to monitor the battery capacity using the AT^SBC command. Failure to comply with these specifications might cause AT^SBC to deliver incorrect battery capacity values. • Li-Ion or Lithium Polymer battery pack specified for a maximum charging voltage of 4.2V and a recommended capacity of 1000 to 1200mAh. • Since charging and discharging largely depend on the battery temperature, the battery pack should include an NTC resistor. If the NTC is not inside the battery it must be in thermal contact with the battery. The NTC resistor must be connected between BATT_TEMP and GND. The B value of the NTC should be in the range: 10kΩ +5% @ 25°C, B25/85 = 3423K to B =3435K ± 3% (alternatively acceptable: 10kΩ +2% @ 25°C, B25/50 = 3370K +3%). Please note that the NTC is indispensable for proper charging, i.e. the charging process will not
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 37 of 97 11.05.2005 start if no NTC is present. • Ensure that the pack incorporates a protection circuit capable of detecting overvoltage (protection against overcharging), undervoltage (protection against deep discharging) and overcurrent. Due to the discharge current profile typical of GSM applications, the circuit must be insensitive to pulsed current. • On the TC63 module, a built-in measuring circuit constantly monitors the supply voltage. In the event of undervoltage, it causes TC63 to power down. Undervoltage thresholds are specific to the battery pack and must be evaluated for the intended model. When you evaluate undervoltage thresholds, consider both the current consumption of TC63 and of the application circuit. • The internal resistance of the battery and the protection should be as low as possible.

The battery cell must be insensitive to rupture, fire and gassing under extreme conditions of temperature and charging (voltage, current). • The battery pack must be protected from reverse pole connection.

Both batteries meet all requirements listed above. They have been thoroughly tested by Siemens, proved to be suited for TC63, and are CE approved. • LIP 633450A1B PCM.STB, type Lithium Ion This battery is listed in the standard product range of VARTA. It is incorporated in a shrink sleeve and has been chosen for integration into the reference setup submitted for Type Approval of Siemens GSM modules. • LPP 503759CA PCM.NTC.LT50, type Lithium Polymer This battery has been especially designed by VARTA for use with Siemens GSM modules. It has the same properties as the above Li-Ion battery, except that it is type Polymer, is smaller and comes without casing. Specifications, construction drawings and sales contacts for both VARTA batteries can be found in Section 9.3. 3.5.5 Charger Requirements For using the implemented charging algorithm and the reference charging circuit recommended in [4] and in Figure 38, the charger has to meet the following requirements: Output voltage: 5.2Volts ±0.2V (stabilized voltage) Output current: 500mA Chargers with a higher output current are acceptable, but please consider that only 500mA will be applied when a 0.3Ohms shunt resistor is connected between VSENSE and ISENSE. See [4] for further details. 3.5.6 Implemented Charging Technique If all requirements listed above are met (appropriate external charging circuit of application, battery pack, charger, AT^SBC settings) then charging is enabled in various stages depending on the battery condition: Trickle charging: • Trickle charge current flows over the VCHARGE line. • Trickle charging is done when a charger is present (connected to VCHARGE) and the battery is deeply discharged or has undervoltage. If deeply discharged (Deep Discharge Lockout at VBATT+= 0…2.5V) the battery is charged with 5mA, in case of undervoltage (Undervoltage Lockout at VBATT+= 2.5…3.2V) it is charged with 30mA Software controlled charging: • Controlled over the CHARGEGATE. • Temperature conditions: 0°C to 45°C • Software controlled charging is done when the charger is present (connected to VCHARGE) and the battery voltage is at least above the undervoltage threshold. Software controlled charging passes the following stages: - Power ramp: Depending on the discharge level of the battery (i.e. the measured battery voltage VBATT+) the software adjusts the maximum charge current for charging the battery. The duration of power ramp charging is very short (less than 30 seconds).
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 39 of 97 11.05.2005 - Fast charging: Battery is charged with constant current (approx. 500mA) until the battery voltage reaches 4.2V (approx. 80% of the battery capacity). - Top-up charging: The battery is charged with constant voltage of 4.2V at stepwise reducing charge current until full battery capacity is reached. • The duration of software controlled charging depends on the battery capacity and the level of discharge. 3.5.7 Operating Modes during Charging Of course, the battery can be charged regardless of the engine's operating mode. When the GSM module is in Normal mode (SLEEP, IDLE, TALK, GPRS IDLE or GPRS DATA mode), it remains operational while charging is in progress (provided that sufficient voltage is applied). The charging process during the Normal mode is referred to as Charge mode. If the charger is connected to the charger input of the external charging circuit and the module’s VCHARGE pin while TC63 is in Power-down mode, TC63 goes into Charge-only mode. While the charger remains connected it is not possible to switch the module off by using the AT^SMSO command or the automatic shutdown mechanism. Instead the following applies: • If the module is in Normal mode and the charger is connected (Charge mode) the AT^SMSO command causes the module to shut down shortly and then start into the Charge-only mode. • In Charge-only mode the AT^SMSO command is not usable. • In Charge-only mode the module neither switches off when the battery or the module exceeds the critical limits of overtemperature or undertemperature. In these cases you can only switch the module off by disconnecting the charger. To proceed from Charge-only mode to another operating mode you have the following options: • To switch from Charge-only mode to Normal mode drive the ignition line (IGT) to ground for 1 second. • To switch from Charge-only mode to Airplane mode enter the command AT^SCFG=MEopMode/Airplane,on. • If AT^SCFG=MEopMode/Airplane/OnStart,on is set, driving the ignition line (IGT) activates the Airplane mode.

All AT commands can be used to full extent. NOTE: If the module operates at maximum power level (PCL5) and GPRS Class 12 at the same time the current consumption is higher than the current supplied by the charger. Charge-only mode Connect charger to charger input of host application charging circuit and module’s VCHARGE pin while TC63 is • in Power-down mode • in Normal mode: Connect charger to the VCHARGE pin, then enter AT^SMSO. NOTE: While trickle charging is in progress, be sure that the host application is switched off. If the application is fed from the trickle charge current the module might be prevented from proceeding to software controlled charging since the current would not be sufficient. • Battery can be charged while GSM engine is deregistered from GSM network. • Charging runs smoothly due to constant current consumption. • The AT interface is accessible and allows to use the commands listed below.

TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 42 of 97 11.05.2005 3.7 RTC Backup The internal Real Time Clock of TC63 is supplied from a separate voltage regulator in the analog controller which is also active when TC63 is in POWER DOWN status. An alarm function is provided that allows to wake up TC63 to Airplane mode without logging on to the GSM network. In addition, you can use the VDDLP pin on the board-to-board connector to backup the RTC from an external capacitor or a battery (rechargeable or non-chargeable). The capacitor is charged by the BATT+ line of TC63. If the voltage supply at BATT+ is disconnected the RTC can be powered by the capacitor. The size of the capacitor determines the duration of buffering when no voltage is applied to TC63, i.e. the larger the capacitor the longer TC63 will save the date and time. A serial 1k resistor placed on the board next to VDDLP limits the charge current of an empty capacitor or battery. The following figures show various sample configurations. Please refer to Table 17 for the parameters required.

TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 43 of 97 11.05.2005 3.8 SIM Interface The baseband processor has an integrated SIM interface compatible with the ISO 7816 IC Card standard. This is wired to the host interface (board-to-board connector) in order to be connected to an external SIM card holder. Six pins on the board-to-board connector are reserved for the SIM interface. The SIM interface supports 3V and 1.8V SIM cards. Please refer to Table 17 for electrical specifications of the SIM interface lines depending on whether a 3V or 1.8V SIM card is used. The CCIN pin serves to detect whether a tray (with SIM card) is present in the card holder. Using the CCIN pin is mandatory for compliance with the GSM 11.11 recommendation if the mechanical design of the host application allows the user to remove the SIM card during operation. To take advantage of this feature, an appropriate SIM card detect switch is required on the card holder. For example, this is true for the model supplied by Molex, which has been tested to operate with TC63 and is part of the Siemens reference equipment submitted for type approval. See Chapter 8 for Molex ordering numbers. Table 7: Signals of the SIM interface (board-to-board connector) Signal Description CCGND Separate ground connection for SIM card to improve EMC. Be sure to use this ground line for the SIM interface rather than any other ground pin or plane on the module. A design example for grounding the SIM interface is shown in Figure 38. CCCLK Chipcard clock, various clock rates can be set in the baseband processor. CCVCC SIM supply voltage. CCIO Serial data line, input and output. CCRST Chipcard reset, provided by baseband processor. CCIN Input on the baseband processor for detecting a SIM card tray in the holder. If the SIM is removed during operation the SIM interface is shut down immediately to prevent destruction of the SIM. The CCIN pin is active low. The CCIN pin is mandatory for applications that allow the user to remove the SIM card during operation. The CCIN pin is solely intended for use with a SIM card. It must not be used for any other purposes. Failure to comply with this requirement may invalidate the type approval of TC63. The total cable length between the board-to-board connector pins on TC63 and the pins of the external SIM card holder must not exceed 100mm in order to meet the specifications of 3GPP TS 51.010-1 and to satisfy the requirements of EMC compliance. To avoid possible cross-talk from the CCCLK signal to the CCIO signal be careful that both lines are not placed closely next to each other. A useful approach is using the CCGND line to shield the CCIO line from the CCCLK line. Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered after removing the SIM card during operation. Also, no guarantee can be given for properly initializing any SIM card that the user inserts after having removed a SIM card during operation. In this case, the application must restart TC63.

It is primarily intended for use as command and data interface and for downloading firmware. The USB I/O-pins are capable of driving the signal at min 3.0V. They are 5V I/O compliant. To properly connect the module’s USB interface to the host a USB 2.0 compatible connector is required. Furthermore, the USB modem driver delivered with TC63 must be installed as described below. The USB host is responsible for supplying, across the VUSB_IN line, power to the module’s USB interface, but not to other TC63 interfaces. This is because TC63 is designed as a self-powered device compliant with the “Universal Serial Bus Specification Revision 2.0”1.

As both operating systems use multiple methods to access modem settings this section provides only a brief summary of the most important steps. Take care that the “usbmodem.inf” file delivered with TC63 is at hand. Connect the USB cable to the TC63 host application (for example the evaluation board DSB75) and the PC. Windows detects TC63 as a new USB modem, opens the Found New Hardware Wizard and reports that it is searching for the “Siemens AG WM USB Modem” driver. Follow the instructions on the screen and specify the path where the “usbmodem.inf” file is located. Windows will copy the required software to your computer and configure the modem by assigning a free COM port. If you are already using more than one COM port then the next free one will be allocated. Click Finish to complete the installation. Notes for Windows 2000 only: • During the installation procedure you will be prompted for the “usbser.sys” driver. Make sure the file is present before you start installing the above inf file. The “usbser.sys” file is not delivered as a single file, but must be extracted from a Windows 2000 cabinet file. This is either the file “driver.cab” located in the “I386” folder of the original Windows 2000 CD or a later cabinet file inside the Service Pack. SP4 for example includes the “sp4.cab” file which can be found in its “I386” folder. The “usbser.sys” driver from the Service Pack has priority over one provided with the standard Windows 2000 install CD. • It is necessary to restart Windows 2000 to make the changes take effect.

Troubleshooting for installation problems If Windows fails to assign the next free COM port to TC63 and, for example, allocates a COM port already used by another modem you can manually select a free port as follows: Open the Windows Device Manager, select the installed “Siemens AG WM USB Modem”, click Properties, select the Advanced tab and click Advanced Port settings. From the listbox COM Port Number choose a free port. To make the changes take effect disconnect and re-connect the USB cable. If not yet successful, also restart Windows.

It consists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK. The TC63 module acts as a single master device, e.g. the clock I2CCLK is driven by module. I2CDAT is a bi-directional line. Each device connected to the bus is software addressable by a unique 7-bit address, and simple master/slave relationships exist at all times. The module operates as master-transmitter or as master-receiver. The customer application transmits or receives data only on request of the module. To configure and activate the I2C interface use the AT^SSPI command described in [1]. To configure and activate the I2C bus use the AT^SSPI command. Detailed information on the AT^SSPI command as well explanations on the protocol and syntax required for data transmission can be found in [1]. The I2C interface can be powered from an external supply or via the VEXT line of TC63. If connected to the VEXT line the I2C interface will be properly shut down when the module enters the Power-down mode. If you prefer to connect the I2C interface to an external power supply, take care that VCC of the application is in the range of VVEXT and that the interface is shut down when the PWR_IND signal goes high. See figures below as well as Section 7 and Figure 38. In the application I2CDAT and I2CCLK lines need to be connected to a positive supply voltage via a pull-up resistor.

This means you can connect up to three different audio devices, although only one interface can be operated at a time. Using the AT^SAIC command you can easily switch back and forth.

The electrical characteristics of the voiceband part vary with the audio mode. For example, sending and receiving amplification, sidetone paths, noise suppression etc. depend on the selected mode and can be altered with AT commands (except for mode 1). Both analog audio interfaces can be used to connect headsets with microphones or speakerphones. Headsets can be operated in audio mode 3, speakerphones in audio mode 2. Audio mode 5 can be used for a speech coder without signal pre or post processing. When shipped from factory, all audio parameters of TC63 are set to interface 1 and audio mode 1. This is the default configuration optimized for the Votronic HH-SI-30.3/V1.1/0 handset and used for type approving the Siemens reference configuration. Audio mode 1 has fix parameters which cannot be modified. To adjust the settings of the Votronic handset simply change to another audio mode.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 53 of 97 11.05.2005 3.13.1 Speech Processing The speech samples from the ADC or DAI are handled by the DSP of the baseband controller to calculate e.g. amplifications, sidetone, echo cancellation or noise suppression depending on the configuration of the active audio mode. These processed samples are passed to the speech encoder. Received samples from the speech decoder are passed to the DAC or DAI after post processing (frequency response correction, adding sidetone etc.). Full rate, half rate, enhanced full rate, adaptive multi rate (AMR), speech and channel encoding including voice activity detection (VAD) and discontinuous transmission (DTX) and digital GMSK modulation are also performed on the GSM baseband processor. 3.13.2 Microphone Circuit TC63 has two identical analog microphone inputs. There is no on-board microphone supply circuit, except for the internal voltage supply VMIC and the dedicated audio ground line AGND. Both lines are well suited to feed a balanced audio application or a single-ended audio application. The AGND line on the TC63 board is especially provided to achieve best grounding conditions for your audio application. As there is less current flowing than through other GND lines of the module or the application, this solution will avoid hum and buzz problems. 3.13.2.1 Single-ended Microphone Input Figure 18 as well as Figure 38 show an example of how to integrate a single-ended microphone input.

The MICNx input is automatically self biased to the MICPx DC level. It is AC coupled via CK to a resistive divider which is used to optimize supply noise cancellation by the differential microphone amplifier in the module.
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 54 of 97 11.05.2005 The VMIC voltage should be filtered if gains larger than 20dB are used. The filter can be attached as a simple first order RC-network (RVMIC and CF). This circuit is well suited if the distance between microphone and module is kept short. Due to good grounding the microphone can be easily ESD protected as its housing usually connects to the negative terminal. 3.13.2.2 Differential Microphone Input Figure 19 shows a differential solution for connecting an electret microphone.

The VMIC voltage should be filtered if gains larger than 20dB are used. The filter can be attached as a simple first order RC-network (RVMIC and CF). The advantage of this circuit is that it can be used if the application involves longer lines between microphone and module.

The VMIC voltage should be filtered if gains larger than 20dB are used. The filter can be attached as a simple first order RC-network (RVMIC and CF). If a high input level and a lower gain are applied the filter is not necessary. If desired, MICNx via CK can also be connected to the inverse output of the AC source instead of connecting it to the reference potential for differential line input.

The signal is generated by the SYNC pin (pin number 32). Please note that this pin can adopt three different operating modes which you can select by using the AT^SSYNC command: the mode AT^SSYNC=0 described below, and the two LED modes AT^SSYNC=1 or AT^SSYNC=2 described in [1] and Section 3.14.2. The first function (factory default AT^SSYNC=0) is recommended if you want your application to use the synchronization signal for better power supply control. Your platform design must be such that the incoming signal accommodates sufficient power supply to the TC63 module if required. This can be achieved by lowering the current drawn from other components installed in your application. The timing of the synchronization signal is shown below. High level of the SYNC pin indicates increased power consumption during transmission. Figure 25: SYNC signal during transmit burst *) The duration of the SYNC signal is always equal, no matter whether the traffic or the access burst are active.

To take advantage of this function the LED mode must be activated with the AT^SSYNC command and the LED must be connected to the host application. The connected LED can be operated in two different display modes (AT^SSYNC=1 or AT^SSYNC=2). For details please refer to [1]. Especially in the development and test phase of an application, system integrators are advised to use the LED mode of the SYNC pin in order to evaluate their product design and identify the source of errors. To operate the LED a buffer, e.g. a transistor or gate, must be included in your application. A sample circuit is shown in Figure 26. Power consumption in the LED mode is the same as for the synchronization signal mode. For details see Table 17, SYNC pin. Figure 26: LED Circuit (Example)
TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 61 of 97 11.05.2005 4 Antenna Interface The RF interface has an impedance of 50. TC63 is capable of sustaining a total mismatch at the antenna connector or pad without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radiated power, DC-power consumption, modulation accuracy and harmonic suppression. Antenna matching networks are not included on the TC63 PCB and should be placed in the host application. Regarding the return loss TC63 provides the following values in the active band: Table 11: Return loss in the active band State of module Return loss of module Recommended return loss of application Receive > 8dB > 12dB Transmit not applicable > 12dB The connection of the antenna or other equipment must be decoupled from DC voltage. This is necessary because the antenna connector is DC coupled to ground via an inductor for ESD protection. 4.1 Antenna Installation To suit the physical design of individual applications TC63 offers two alternative approaches to connecting the antenna: • Recommended approach: U.FL-R-SMT antenna connector from Hirose assembled on the component side of the PCB (top view on TC63). See Section 4.3 for details. • Antenna pad and grounding plane placed on the bottom side. See Section 4.2. The U.FL-R-SMT connector has been chosen as antenna reference point (ARP) for the Siemens reference equipment submitted to type approve TC63. All RF data specified throughout this manual are related to the ARP. For compliance with the test results of the Siemens type approval you are advised to give priority to the connector, rather than using the antenna pad. IMPORTANT: Both solutions can only be applied alternatively. This means, whenever an antenna is plugged to the Hirose connector, the pad must not be used. Vice versa, if the antenna is connected to the pad, then the Hirose connector must be left empty.

TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 63 of 97 11.05.2005 4.2 Antenna Pad The antenna can be soldered to the pad, or attached via contact springs. For proper grounding connect the antenna to the ground plane on the bottom of TC63 which must be connected to the ground plane of the application. When you decide to use the antenna pad take into account that the pad has not been intended as antenna reference point (ARP) for the Siemens TC63 type approval. The antenna pad is provided only as an alternative option which can be used, for example, if the recommended Hirose connection does not fit into your antenna design. Also, consider that according to the GSM recommendations TS 45.005 and TS 51.010-01 a 50 connector is mandatory for type approval measurements. This requires GSM devices with an integral antenna to be temporarily equipped with a suitable connector or a low loss RF cable with adapter. Notes on soldering: • To prevent damage to the module and to obtain long-term solder joint properties you are advised to maintain the standards of good engineering practice for soldering. • Be sure to solder the antenna core to the pad and the shielding of the coax cable to the ground plane of the module next to the antenna pad. The direction of the cable is not relevant from the electrical point of view. TC63 material properties: TC63 PCB: FR4 Antenna pad: Gold plated pad 4.2.1 Suitable Cable Types For direct solder attachment, we suggest to use the following cable types: • RG316/U 50Ohm coaxial cable • 1671A 50Ohm coaxial cable Suitable cables are offered, for example, by IMS Connector Systems.

The possible deviation is in a range of: • ± 3°C at the overtemperature limit • ± 5°C at the undertemperature limit *) On TC63 the automatic overtemperature shutdown threshold is set to 90°C board temperature. This prevents permanent damage to components on the board. Consider the ratio of output power, supply voltage and operating temperature: to achieve Tamb max = 65°C in GPRS Class 8 (GSM900/ GSM850) with 2W RF power the supply voltage must not be higher than 4.2V.

Consequently, it is subject to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates a TC63 module. Special ESD protection provided on TC63: Antenna interface: one spark discharge line (spark gap) SIM interface: clamp diodes for protection against overvoltage. The remaining ports of TC63 are not accessible to the user of the final product (since they are installed within the device) and therefore, are only protected according to the “Human Body Model” requirements. TC63 has been tested according to the EN 61000-4-2 standard. The measured values can be gathered from the following table. Table 21: Measured electrostatic values Specification / Requirements Contact discharge Air discharge ETSI EN 301 489-7 ESD at SIM port ± 4kV ± 8kV ESD at antenna port ± 4kV ± 8kV Human Body Model (Test conditions: 1.5kΩ, 100pF) ESD at USB interface ± 1kV ± 1kV ESD at all other interfaces ± 1kV ± 1kV Note: Please note that the values may vary with the individual application design. For example, it matters whether or not the application platform is grounded over external devices like a computer or other equipment, such as the Siemens reference application described in Chapter 8.

TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 82 of 97 11.05.2005 6.2 Mounting TC63 to the Application Platform There are many ways to properly install TC63 in the host device. An efficient approach is to mount the TC63 PCB to a frame, plate, rack or chassis. Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or brackets. In addition, the board-to-board connection can also be utilized to achieve better support. To help you find appropriate spacers a list of selected screws and distance sleeves for 3mm stacking height can be found in Section 9.2. When using the two small holes take care that the screws are inserted with the screw head on the bottom of the TC63 PCB. Screws for the large holes can be inserted from top or bottom. For proper grounding it is strongly recommended to use large ground plane on the bottom of board in addition to the five GND pins of the board-to-board connector. The ground plane may also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape. To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat against the host device. All the information you need to install an antenna is summarized in Chapter 4. Note that the antenna pad on the bottom of the TC63 PCB must not be influenced by any other PCBs, components or by the housing of the host device. It needs to be surrounded by a restricted space as described in Section 4.1.

TC63 Hardware Interface Description Strictly confidential / Draft s TC63_HD_V00.432 Page 86 of 97 11.05.2005 7 Sample Application Figure 38 shows a typical example of how to integrate a TC63 module into the GSM part of a mobile application. Usage of the various host interfaces depends on the desired features of the application. Audio interface 1 demonstrates the balanced connection of microphone and earpiece. This solution is particularly well suited for internal transducers. Audio interface 2 uses an unbalanced microphone and earpiece connection typically found in headset applications. The charging circuit is optimized for the charging stages (trickle charging and software controlled charging) as well as the battery and charger specifications described in Section 3.5. The PWR_IND line is an open collector that needs an external pull-up resistor which connects to the voltage supply VCC µC of the microcontroller. Low state of the open collector pulls the PWR_IND signal low and indicates that the TC63 module is active, high level notifies the Power-down mode. If the module is in Power-down mode avoid current flowing from any other source into the module circuit, for example reverse current from high state external control lines. Therefore, the controlling application must be designed to prevent reverse flow. The internal pull-up resistors (Rp) of the I2C interface can be connected to an external power supply or to the VEXT line of TC63. The advantage of this solution is that when the module enters the Power-down mode, the I2C interface is shut down as well. If you prefer to connect an I2C interface to an external power supply, take care that the interface is shut down when the PWR_IND signal goes high in Power-down mode. The EMC measures are best practice recommendations. In fact, an adequate EMC strategy for an individual application is very much determined by the overall layout and, especially, the position of components. For example, mounting the internal acoustic transducers directly on the PCB eliminates the need to use the ferrite beads shown in the sample schematic. However, when connecting cables to the module’s interfaces it is strongly recommended to add appropriate ferrite beads for reducing RF radiation. Disclaimer No warranty, either stated or implied, is provided on the sample schematic diagram shown in Figure 38 and the information detailed in this section. As functionality and compliance with national regulations depend to a great amount on the used electronic components and the individual application layout manufacturers are required to ensure adequate design and operating safeguards for their products using TC63 modules.
