98-08901C66-G 72. INTRODUCTION2.1 GENERAL DESCRIPTIONThe g20 is Motorola’s newest family of embedded cellular products. Motorola continues its tradition of excellence byintroducing this new cellular engine family for GSM/GPRS communications, consisting of the d10, the d15 and the g18.The new module is similar to a condensed cellular phone core, and can be integrated in any system or product that needs totransfer voice or data information. Thus, it significantly enhances the system’s capabilities, transforming it from a standalone,isolated product to a powerful component connected to communication nets.The new g20 is extremely small in dimensions, yet packed with a host of highly-advanced features designed to facilitate fastand easy integration with OEM user products. It significantly shortens the development process for OEM developers, thanks toits wide range of built-in applications, and minimizes the product’s time to market.The g20 module is ideally suited for the automotive, telemetry, security, insurance and EPOS industries, for delivery andhandheld terminals, and for PDA markets.2.2 TERMS AND ABBREVIATIONSThis section provides definitions for terms and acronyms used in this document.

HARDWARE DESCRIPTION3.1 G20 BLOCK DIAGRAM DESCRIPTION AND OPERATION OVERVIEWThis chapter describes the basic blocks comprising the g20 module and the connectivity options for the module.3.1.1 g20 Block DiagramFigure 1 shows a block diagram for the g20 module:Figure 1. g20 Block DiagramThe g20 consists of the following blocks:•Power and Audio Management IC: This block is responsible for the power on/off process, analog audio drivers, internalregulators, realtime clock activities, and the battery charging process. When an On command is received, this IC wakes upthe internal regulators and controls the reset process. This activity turns the unit on. When an Off command is received, thisIC sends the request to the main processor, which in turn shuts down the unit in an orderly fashion. During shutdown, theunit is disconnected from the network, all tasks are terminated and the regulators are shut down. The on/off inputs (On/Offand Ignition) are always on, even when the unit is off.

98-08901C66-G 173.2 POWER SUPPLY AND CURRENT CONSUMPTIONThis section describes the following power-related considerations for the g20:• Power supply design• g20 current consumption• Turning the unit on/off• Sleep mode options3.2.1 Power Supply DesignThe following power supply design considerations apply to the g20:• The g20 is designed to operate between 3.0 V to 4.2 V on the g20 input (after all losses). In order to reduce battery powerconsumption, it is important to verify power supply line and regulator losses in the PCB.• The g20 is a GSM/GPRS phone that transmits in 0.5 ms pulses every 4.6 ms. The peak current is approximately 2.0 A.• When the power supply is lower than 2.85 V, the g20 software determines that the battery is low and disconnects the unit.• When the voltage is greater than 4.25 V, the g20 software detects an over voltage condition and does not allow the unit toestablish a call.• The VCC line typically drops during TX periods.Figure 5. VCC Signal During TX PeriodsTo minimize the ∆, it is recommended to use lines that are as short as possible, and to place a 1000uF capacitor (or the maximumpossible) in the g20 VCC input. (When a battery is used, there is no need for a large capacitor.)It is recommended to keep the ∆ less than 0.3 V.3.2.1.1 Power Supply RF FilteringIt is recommended to add RF filtering to the DC lines.Use 100nF, 39pF, 22pF or 8.2pF capacitors in parallel to the power supply lines (close to the g20 connector). The followingcapacitor requirements apply:• 100nF is for filtering logic data noise (clocks, serial communications, and so on).• 39pF is used for 850/900 bands.• 22pF is used for 900 band.• 8.2pF is used for 1800/1900 bands.The appropriate capacitor value(s) should be selected according to the GSM band used by the customer.NoteThe power supply should be able to drive at least 2.5 A at 3 V DC.TransmitPeriods VCCTX TX TX
18 98-08901C66-G3.2.2 g20 Current Consumption In order to design the power supply correctly and to calculate the battery life, you should take into account the currentconsumption of the g20 when operating in different modes.3.2.3 Turning the Unit On/OffTwo different mechanisms are available to turn the g20 on and off:• On/Off signal (Pin 53)• Ignition signal (Pin 51)Table 4. g20 Current ConsumptionMode Current Consumption (mA RMS)g20 in Sleep mode (camped and Sleep-mode enabled)< 2.5 mA, RMS @ DRX9, Typical 2.2 mA< 4.5 mA, RMS @ DRX2, Typical 3.5 mAg20 during search time < 40 mA, RMS, Typical 25 mA, RMSg20 off < 100 uA – Typical 25 uAg20 during a callGSM 900 @ Power level #5 < 350 mA, Typical 270 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mAGSM 850 @ Power level #7 < 250 mA, Typical 185 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mADCS 1800 @ Power level #0 < 300 mA, Typical 220 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mAPCS 1900 @ Power level #5 < 300 mA, Typical 240 mA@ Power level #10, Typical 160 mA@ Power level #19, Typical 135 mANoteDRX2/9 is the rate used by the base station to query the mobile station. The network operator sets this parameter.NoteThe g20 power-on and power-off timing may vary slightly, depending on the software version.
98-08901C66-G 193.2.3.1 On/Off SignalThe on/off signal is an active-low toggle switch. After power is applied to the g20, the on/off signal is pulled high to VCC byan internal 200KΩ resistor.To turn the g20 on, the on/off signal should be pulled low for a minimum of 800 ms (T1). This will initiate the power-on process,which lasts about five seconds, after which the g20 is ready to communicate.To turn the g20 off, the on/off signal should be pulled low for a minimum of two seconds. This will initiate the power-offprocess, which lasts about eight seconds, after which the g20 will shut down. The g20 can be turned off only if at least 10 secondshave elapsed since the last power on.Figure 6 shows the timing diagram for the on/off signal.Figure 6. On/Off Signal Timing DiagramIn Figure 6, the following timing requirements apply:• T1 minimum = 800 ms.• T2 minimum = 10 seconds.• T3 minimum = 2 seconds.3.2.3.2 Ignition SignalThe ignition signal turns the g20 on and off, depending on its logic state.To turn the g20 on, the ignition signal must be pulled high. This initiates the power-on process, which lasts about five seconds,after which the g20 is ready to communicate. The g20 remains active for the duration of the ignition signal remaining high.To turn the g20 off, the ignition signal must be pulled low. This initiates the power-off process, which may last up to 30 seconds,after which the g20 will shut down. The ignition signal must remain low for the duration of the power-off process, until the g20shuts down. Otherwise, the power-off process may be interrupted or may not complete.3.2.4 Sleep Mode OptionsThis section describes how the g20 can be awakened by the DTE and vice-versa.The DCE (g20) and the DTE can incorporate a sleep mechanism in their application in order to conserve battery life.Sleep mode enables the g20 to be awakened when the DTE wants to communicate with it. Conversely, it also enables the DTEto be awakened by the g20 when the g20 wants to communicate with it. The g20 will not enter sleep mode if the USB isconnected.3.2.4.1 General• The g20 Sleep Mode option can be enabled or disabled using ATS24. • Sleep mode is activated by sending ATS24 = n, where n = 1, 2, 3 or 4 seconds. (To disable Sleep mode, send ATS24=0.) • The g20 drops the CTS (h/w Flow Control) when it is in Sleep mode. • The g20 does not enter Sleep mode when data is present on TXD or RXD lines.• At the end of the TXD (meaning, the TXD buffer is empty), the g20 waits n seconds (as defined in ATS24 = n) before enter-ing Sleep mode.T1 T2 T3
20 98-08901C66-G• The DTE uses CTS to send data only when the g20 is awake. The DTE waits when the g20 is in Sleep mode.• When the g20 is asleep, the CTS line will blink.• The DTE should drop RTS during the sleep period in order to prevent the loss of data sent by the g20.Figure 7. CTS Sleep Mode Timing3.2.4.2 DCE/DTE ConnectivityFigure 8 shows DCE/DTE connectivity:Figure 8. DCE/DTE ConnectivityWaking Up the g20:The following apply when waking up the g20:• The Wake-up In line is used to awaken the g20. This input is routed into an Interrupt in the g20.• Whenever the Wake-up In line is at logic “low”, the g20 remains in an awake state.• When the DTE needs to send data, it should activate this line, wait 30 ms (the wake time required for the g20), and then startsending the data.InactiveSleepInactiveSleepActiveAwakeActiveAwakeg20 Sleep PeriodsCTSg20(DCE)UserUART(DTE)RTSCTSTXDWake-up OutWake-up In915212616
98-08901C66-G 21• While the DTE is sending data, the wake-up line should remain low, so that the g20 does not enter Sleep mode.Figure 9. Waking Up the g20 when the DTE wants to Send DataWaking Up the DTE:The following apply when waking up the DTE:• The g20 uses the Wake-up Out line to indicate to the DTE that data is present. • The DTE should not enter Sleep mode when the Wake-up Out line is low.• When the g20 has data to send to the DTE, it drops the Wake-up Out line to low.• The g20 will send the Wake-up Out line #ms to low, as indicated by S102 in Figure 10.• While the g20 is sending data, the Wake-up Out line remains low. • After the sending of data is completed, the g20 brings the Wake-up Out line to high.• The DTE should keep RTS off during this sleep period in order to avoid sending data when it is not ready.Figure 10. Waking Up the DTE when the g20 wants to Send Data3.3 COMMUNICATION INTERFACESThis section describes the following four interfaces that are available in the g20:• RS232•USB•SIM•SPIDTE TXDWake-up In line30 ms 30 ms 30 msRXDWake-upOut lineS102 ms S102 ms S102 ms
22 98-08901C66-G3.3.1 RS232The following apply when using the RS2332 interface of the g20:• The g20 supports full hardware flow control (8 pins), software flow control (Xon/Xoff) and non-flow control.• The g20 UART is connected directly to the interface connector.• The g20 is a DCE device. Applicable line terminology is shown in Figure 11.Figure 11. g20 RS232 Interface3.3.1.1 RS232 LevelsRS232 levels are as follows:• Vih = 1.95 V minimum, 3.0 V maximum• Vil = 0.8 V maximum• Voh = 2.56 V minimum @ 100 uA• Vol = 0.2 V maximum @ 100 uA3.3.1.2 RS232 ConnectionAs shown in Figure 12, the g20 can be connected to the DTE UART using all eight RS232 signals.The g20 selects its communication channel, RS232 or USB, depending on the state of the USB_VBUS signal (pin 10) at powerup. The g20 operates in RS232 mode if the USB_VBUS signal is low at power up and remains low during operation.The g20 does not support dynamic switching between RS232 and USB channels during operation, and does not supportsimultaneous operation.NoteA buffer is required whenever DTE levels do not match g20 levels (not 5V tolerant).NoteWhen the g20 is switched off, it is recommended to keep the RS232 signals of the DTE at tri-state or at a low levelin order to prevent potential latch-up.g20(DCE)UserUART(DTE)TXDRXDRTSCTSDTRDSRDCDRI211191519131723
98-08901C66-G 233.3.2 USBThe g20 selects its communication channel, RS232 or USB, depending on the state of the USB_VBUS signal (pin 10) at powerup. The g20 operates in USB mode if the USB_VBUS signal is high at power up and remains high during operation. TheUSB_VBUS signal is the power line of the USB interface, which powers the USB circuitry.The g20 does not support dynamic switching between RS232 and USB channels during operation, and does not supportsimultaneous operationWhen USB is used, the DTE device must unload (meaning disconnect or place in tri-state) the RS232 lines. Otherwise, the USBmay not operate properly.The USB port is also used to load software into the g20. It is recommended to include connectivity to this port in the userapplication.The g20 supports USB 1.1 at a baud rate of 12 Mbps.3.3.2.1 USB ConnectionA USB connection diagram is shown in Figure 12.Figure 12. g20 USB Connection for g20 ModelsAs shown in Figure 12, the g20 USB is connected via three lines to the USB connector in the user application: D+, D- and USBVBUS. When USB VBUS is applied, the g20 detects it and switches the main processor to USB mode.NoteThe DTE UART loads the USB driver/main processor lines. Therefore, the UART should be kept in tri-state.USB usage eliminates sleep mode in the g20.g20 MainProcessorUSBDriverD+D-USB VBUSUSBDetectTXDRXDRTSCTSDTRDSRDCDRIUSBConnector3 stateg20 DTEUARTUSBMUXDTEUART211191519131723121410
24 98-08901C66-G3.3.3 SIMThe g20 includes a SIM card driver, however, it does not contain a SIM socket. SIM signals are routed to the interface connectorand include all the functionality required for SIM card operation. The SIM card socket must be located in the customerapplication, and connected to the g20 interface connector as described in the following section.3.3.3.1 SIM ConnectionFigure 13 shows a g20 SIM connection:Figure 13. g20 SIM ConnectionThe following apply for g20 SIM connections:• The g20 passes all ETSI tests when an external socket is connected to the g20 with lines shorter than 10 cm. Longer signalconnections may require additional testing to be performed.• The g20 supports 3.0V and 1.8V SIM cards.• The SIM card detect signal, SIM_PD, operates in active low logic.The SIM card signals must be carefully routed to minimize ESD and EMI susceptibility. The following are guidelines for properSIM application operation:• The SIM ground must be connected to the main ground through an inductive element.• The SIM card socket should be located away from the antenna as far as possible.• The SIM logic signals, DIO, CLK, RST and PD, may need to be filtered with 10pF capacitors, depending on the applicationand its distance from the antenna.• The SIM detect signal, SIM_PD, should be connected to the g20 through a 15uH inductor.• Low capacitance zener diodes should be placed as close as possible to the SIM card socket contacts, for proper ESDprotection.
98-08901C66-G 253.3.4 SPIThe SPI is a standard microprocessor bus used as a g20 debugging port. This port activates a debug option that enables logs tobe taken from the g20 while it is operating. It is recommended that this bus be accessible in the user application. In the g20Developer’s Kit, the SPI bus is converted to an RS232 protocol using a special interface circuit. It then uses the standard RS232port for debugging. Table 5 shows the pins available on the SPI bus.3.3.4.1 SPI Connection3.3.5 Unique g20 InterfacesThe g20 contains unique functions (pins) that may be required by selected user applications, such as TX_EN, Antenna Detect,GPRS Detect and Entertainment Mute. Each of these functions is described in the sections that follow.3.3.5.1 Transmit EnableThis pin indicates when the g20 is transmitting RF in the antenna.Figure 14. TX_EN Transmission3.3.5.2 GPRS Coverage IndicationThis pin indicates whether or not the g20 is located in an area with GPRS network coverage. This pin can be used to indicatethe GPRS coverage status before GPRS section activation has occurred, or before a switch to circuit-switched data is made. Thedefault operation of this signal is active low, meaning this signal is at 0 when GPRS coverage is available. It is possible to switchthe signal’s polarity to active high using an AT command. Refer to the g20 AT Commands document (9808901C68-O) for theAT commands description.Table 5.

26 98-08901C66-G3.3.5.3 Antenna DetectThis pin indicates whether or not the antenna is inserted. This option can be used with antennas with a resistance to ground ofless than 100K. The antenna detect circuit detects whether the ohmic resistance of the antenna is 100 Kohm or lower, which isrequired for the antenna to be detected. If the ohmic resistance is higher than 100 Kohm, the antenna is not detected.In software versions 34D and later, this signal has been collaborated to match the logic detection threshold of the g20, andexhibits best results when connected back to the g20. A dedicated g20 input signal, pin 37, is available for the antenna detectioninput. This is to ensure proper operation of the antenna-detect AT command, which enables software indication of the antennastate. Figure 15. Antenna Detect3.4 AUDIO INTERFACESThe g20 has an analog audio interface and a digital audio interface. Both of these interfaces are described in the sections thatfollow.3.4.1 Analog Audio InterfacesThe g20 supports microphone input, headset microphone input, differential speaker output, and a differential alert speaker.3.4.1.1 Analog InputThe g20 has two different analog inputs, referenced to the microphone ground (pin 59). The g20 contains an analog amplifierwith a default gain of 16dB, which can be adjusted in seven steps between 0 and 31dB using the AT+MMICG command. Formore details about this command, refer to the g20 AT Commands document (9808901C68).When the default gain of 16dB is used, then the level considerations should be as follows:•Headset microphone: Pin 57 is the headset microphone input. The input for this line can come directly from a headsetmicrophone. In order for the headset microphone to be active, the headset interrupt signal (pin 55) needs to be pulled low.The maximum input to the g20 headset microphone before there is signal distortion in the network is 12 mvRMS.•Hands-free microphone: Pin 61 is the microphone input to the g20. When the headset interrupt signal is not pulled low,this microphone will be active. The maximum input to the g20 microphone before there is signal distortion in the network is32 mvRMS.3.4.1.2 Analog OutputThe g20 has a differential speaker output and an alert output:•Speaker output: When headset mode is used, the headset speaker should be connected to the SPKR_N signal of the g20.When a differential amplifier is used, both lines should be connected. An 8-ohm speaker can be connected directly to thespeaker lines.•Alert: The g20 supports a direct connection for an alert transducer, in order to build a handset from the g20. All the soundsthat are transmitted to the alert can be routed to the speaker using the appropriate AT command.Antenna DetectedAntenna Not Detected

If a microphone with a different voltage isused, the bias should be as clean as possible, and referenced to MIC_GND. Because most GSM buzz (217Hz TDMA noise)is generated from the microphone path, if a different bias is created, it should be filtered to supply DC only.• The MIC_GND and GND are connected inside the g20 and should not be connected to the application board.• Keep the lines of the microphone inputs as short as possible. To filter the lines from RF emission, 39pF capacitors can beused.• The g20 GND should be connected on all four pins, with two mounting screws to the application ground.• If possible, the RF cable ground from the g20 should be connected to the GND of the g20.• The digital lines of the application should never be referenced to the MIC_GND.3.4.2 Digital Audio InterfaceThe g20 digital audio interface is a full-duplex SAP (serial audio port) comprised of four signals:•PCM_FS: This pin is used for frame sync output provided by the g20.•PCM_CLK: This pin is used for the clock output provided by the g20.•PCM_DIN: This pin is the serial input to the g20 SAP.•PCM_DOUT: This pin is the serial output of the g20 SAP.Table 11. Alert Transducer Levels for the ALERT_P SignalHandset Volume ALRT_P (mV RMS)0871124217532504350548766807980
98-08901C66-G 31The following conditions apply to the digital audio interface of the g20:• The g20 SAP works in network mode, with four slots in each frame. Each slot consists of 16-bit data.• The g20 sends and receives data on the first slot only.• The frame sync rate is 8 KHz, and the clock rate is 512 KHz. • The g20 is the master in the SAP network. Therefore, the connected DSP should be configured as a slave.• Digital audio lines should be connected to Codex or DSP on the application side.3.5 ANTENNAThe g20 has two models, one for North America Frequency bands (850/1900 MHz), and one for European Bands (900/1800 MHz). The following connection requirements apply for the g20 antenna:• The g20 is terminated with an MMCX connector, and with 50-ohm impedance in the relevant frequencies.• The g20 can be connected to any antenna with 50-ohm impedance in the relevant frequency bands.• The g20 is designed to work on VSWR, up to 2:5:1 The antenna should meet this requirement.3.5.1 Antenna Performance RecommendationsTable 12 lists the performance recommendations for the g20 antenna.3.6 ESD PROTECTIONIn general, the g20 does not include embedded ESD protection circuits. This type of protection should be implemented in thecustomer application. Partial ESD protection is provided, as follows:• SIM lines are protected up to 3 KV with 6.8 V Zener Diodes.• VCC input is protected with a 2.2 uF capacitor.• Ignition input is protected with a 100 nF capacitor.Table 12.

The test is performed in order to:• Introduce the user to the g20• Explain how to work with the g20 unit• Describe how to evaluate basic g20 featuresThe test setup provides a wide platform through which a g20 unit can be evaluated. The specific test procedure described belowcovers only few of the g20’s many features. Using this setup, you can perform several additional tests on the g20.The test is performed using two modems, one of which is the g20. The modems communicate with each other through a singlecomputer, which also controls their operation.The test requires knowledge about the operation of the g20 Developer’s Kit, terminal applications and AT commands. Refer torelevant documentation for assistance.To perform the test, you need the following:• A g20 OEM cellular engine unit• A g20 Developer's Kit• A desktop or laptop computer, which includes:•· A free serial communications port (RS232)•· A connected and active line modem (internal or external)•· A terminal application (such as HyperTerminal)
46 98-08901C66-G6.2.1 Test SetupFollow the procedure below to set up your equipment before performing the test:1. Verify that the computer you intend to use for the test is equipped with a working line modem.*2. Set up the g20 and the Developer Board as described in the Initial Setup section of the g20 Developer’s Kit document bydoing the following: • Verify that the g20 has adequate reception from the local GSM network.• Connect the Developer Board’s RS232 port to the computer’s serial port.3. Open a terminal application window (such as HyperTerminal) in the computer and configure it to operate with the serialport occupied by the g20.4. Open a second terminal window and configure it to operate with the serial port occupied by the line modem.Figure 18. Test Setup*You can use a second g20 unit instead of the line modem. When doing so, you must repeat the setup procedure for the additional g20.6.2.2 Test ProcedureFollow the procedure below to perform the g20 test:1. Verify that the g20 is functioning and communicating with the computer by performing the following AT commands in the g20 terminal window:•ati7: This prompts g20 identification. The g20 will reply "G20 OEM Module".•ati8: This command prompts the g20 software version.2. Verify that the line modem is functioning and communicating with the computer by entering the AT command "at" in themodem’s terminal window. This common AT command prompts a properly working modem to reply "OK".3. Make a CSD data call from the g20 to the line modem or vice versa using the "atdt" and "ata" commands in the appropriatewindow.4. Verify that a connection between the two modems is established.5. Select any file to be transferred between the two modems. The file can be any existing file on the computer, or a new filecreated specifically for the test.6. Send the file through the terminal application, from the g20 or to it, using the terminal application’s send/receive fileoptions.7. When the file transfer is completed, use the "ath" command in any of the terminal windows to terminate the call. This stepcompletes the test. You can now continue to perform additional tests using the same setup, or change the setup as required.Computer Developer Boardwith g20 unitLine Modem(internal or external)To telephone line wall outlet RS232PortSerialPortSerialPortSerialCable
