EHS6 Hardware Interface Overview2 Interface Characteristics21EHS6_HIO_v01.441 Page 10 of 38 2013-07-11Confidential / Preliminary2 Interface CharacteristicsEHS6 is equipped with an SMT application interface that connects to the external application. The SMT application interface incorporates the various application interfaces as well as the RF antenna interface. 2.1 Application Interface2.1.1 USB InterfaceEHS6 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) compliant. The USB interface is primarily intended for use as command and data interface and for downloading firmware. The USB host is responsible for supplying the VUSB_IN line. This line is for voltage detection only. The USB part (driver and transceiver) is supplied by means of BATT+. This is because EHS6 is designed as a self-powered device compliant with the “Universal Serial Bus Specifi-cation Revision 2.0”1.Figure 2: USB circuitTo properly connect the module's USB interface to the host a USB 2.0 compatible connector is required. Furthermore, the USB modem driver distributed with EHS6 needs to be installed.1. The specification is ready for download on http://www.usb.org/developers/docs/VBUSDPDNVREG (3V075)BATT+USB_DP2)lin. reg.

Application layout should in this case implement a differential impedance of 90Ohm for proper signal integrity.RSRSSMT

EHS6 Hardware Interface Overview2.1 Application Interface21EHS6_HIO_v01.441 Page 11 of 38 2013-07-11Confidential / PreliminaryWhile the USB connection is active, the module will not change into SLEEP Mode. To enable switching into SLEEP mode the USB host must bring its USB interface into Suspend state. Al-so, VUSB_IN should always be kept enabled for this functionality. See “Universal Serial Bus Specification Revision 2.0“1 for a description of the Suspend state. On incoming calls EHS6 will then generate a remote wake up request to resume the USB connection (active low).As an alternative to the regular USB remote wakeup mechanism it is possible to employ the RING0 line to wake up the host application. The benefit is that the RING0 line can wake up the host application in case of incoming calls or other events signalized by URCs while the USB interface is suspended or shut down. 2.1.2 Serial Interface ASC0EHS6 offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to ITU-T V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or in-active state). EHS6 is designed for use as a DCE. Based on the conventions for DCE-DTE connections it communicates with the customer application (DTE) using the following signals:• Port TXD @ application sends data to the module’s TXD0 signal line• Port RXD @ application receives data from the module’s RXD0 signal lineFigure 3: Serial interface ASC0Features:• Includes the data lines TXD0 and RXD0, the status lines RTS0 and CTS0 and, in addition,the modem control lines DTR0, DSR0, DCD0 and RING0.• ASC0 is designed for controlling GSM/UMTS voice calls, transferring data and for control-ling the module with AT commands.• Full multiplexing capability allows the interface to be partitioned into virtual channels.• The RING0 signal serves to indicate incoming calls and other types of URCs (UnsolicitedResult Code). It can also be used to send pulses to the host application, for example to

The hardware hand shake line RTS0 has aninternal pull down resistor causing a low level signal, if the line is not used and open.Although hardware flow control is recommended, this allows communication by using onlyRXD and TXD lines.• Wake up from SLEEP mode by RTS0 activation (high to low transition).2.1.3 Serial Interface ASC1Four EHS6 GPIO lines can be configured as ASC1 interface signals to provide a 4-wire unbal-anced, asynchronous modem interface ASC1 conforming to ITU-T V.24 protocol DCE signal-ling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state). EHS6 is designed for use as a DCE. Based on the conventions for DCE-DTE connections itcommunicates with the customer application (DTE) using the following signals:• Port TXD @ application sends data to module’s TXD1 signal line• Port RXD @ application receives data from the module’s RXD1 signal lineFigure 4: Serial interface ASC1Features• Includes only the data lines TXD1 and RXD1 plus RTS1 and CTS1 for hardware hand-shake. • On ASC1 no RING line is available.• Configured for 8 data bits, no parity and 1 or 2 stop bits.• ASC1 can be operated at fixed bit rates from 1,200 bps to 921,600 bps. • Autobauding supports bit rates from 1,200bps up to 230,400bps. • Supports RTS1/CTS1 hardware flow. The hardware hand shake line RTS0 has an internalpull down resistor causing a low level signal, if the line is not used and open. Although hard-ware flow control is recommended, this allows communication by using only RXD and TXDlines.

EHS6 Hardware Interface Overview2.1 Application Interface21EHS6_HIO_v01.441 Page 13 of 38 2013-07-11Confidential / Preliminary2.1.4 UICC/SIM/USIM InterfaceEHS6 has an integrated UICC/SIM/USIM interface compatible with the 3GPP 31.102 and ETSI 102 221. This is wired to the host interface in order to be connected to an external SIM card holder. Five pads on the SMT application interface are reserved for the SIM interface. The UICC/SIM/USIM interface supports 3V and 1.8V SIM cards.The CCIN signal serves to detect whether a tray (with SIM card) is present in the card holder. Using the CCIN signal 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 oper-ation. 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 test-ed to operate with EHS6 and is part of the Cinterion reference equipment submitted for type approval. See Section 7.1 for Molex ordering numbers.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 initializ-ing any SIM card that the user inserts after having removed the SIM card during operation. In this case, the application must restart EHS6.Table 1: Signals of the SIM interface (SMT application interface)Signal DescriptionGND Separate ground connection for SIM card to improve EMC.CCCLK Chipcard clockCCVCC SIM supply voltage.CCIO Serial data line, input and output.CCRST Chipcard resetCCIN 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 destruc-tion of the SIM. The CCIN signal is by default low and will change to high level if a SIM card is inserted.The CCIN signal is mandatory for applications that allow the user to remove the SIM card during operation. The CCIN signal 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 EHS6.

EHS6 Hardware Interface Overview2.1 Application Interface21EHS6_HIO_v01.441 Page 14 of 38 2013-07-11Confidential / PreliminaryThe figure below shows a circuit to connect an external SIM card holder.Figure 5: External UICC/SIM/USIM card holder circuitThe total cable length between the SMT application interface pads on EHS6 and the pads 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 a GND line to shield the CCIO line from the CCCLK line.2.1.5 Digital Audio InterfaceEHS6‘s digital audio interface (DAI) can be used to connect audio devices capable of pulsecode modulation (PCM). 2.1.6 GPIO InterfaceEHS6 offers a GPIO interface with 22 GPIO lines. The GPIO lines are shared with other inter-faces resp. functions: Fast shutdown (see Section 2.1.13), status LED (see Section 2.1.12), thePWM functionality (see Section 2.1.10), an pulse counter (see Section 2.1.11), ASC0 (see Sec-tion 2.1.2), ASC1 (see Section 2.1.3), an SPI interface (see Section 2.1.8), an HSIC interface(see Section 2.1.9) and a PCM interface (see Section 2.1.5) The following table shows the configuration variants for the GPIO pads. All variants are mutu-ally exclusive, i.e. a pad configured for instance as Status LED is locked for alternative usage.SIMCCVCCCCRSTCCIOCCCLK220nF1nFCCINV180

EHS6 Hardware Interface Overview2.1 Application Interface21EHS6_HIO_v01.441 Page 15 of 38 2013-07-11Confidential / PreliminaryWhen the EHS6 starts up, all GPIO lines (except GPIO1-GPIO3 and GPIO24) are set to high-impedance state after initializing. Therefore, it is recommended to connect external pull-up orpull-down resistors to those GPIO lines that are to be used as output. This is necessary to keepthese lines from floating or driving any external devices.Table 2: GPIO lines and possible alternative assignmentGPIO Fast Shutdown Status LED PWM Pulse Counter ASC0 ASC1 SPI HSIC PCMGPIO1 DTR0GPIO2 DCD0GPIO3 DSR0 SPI_CLKGPIO4 FST_SHDNGPIO5 Status LEDGPIO6 PWM2GPIO7 PWM1GPIO8 COUNTERGPIO11GPIO12GPIO13GPIO14GPIO15GPIO16 RXD1 MOSI AP_WAKEUPGPIO17 TXD1 MISO HOST_ACTIVEGPIO18 RTS1 CP_WAKEUPGPIO19 CTS1 SPI_CS SUSPENDGPIO20 TXDDAIGPIO21 RXDDAIGPIO22 TFSDAIGPIO23 SCLKGPIO24 RING0

EHS6 Hardware Interface Overview2.1 Application Interface21EHS6_HIO_v01.441 Page 16 of 38 2013-07-11Confidential / Preliminary2.1.7 I2C InterfaceI2C is a serial, 8-bit oriented data transfer bus for bit rates up to 400kbps in Fast mode. It con-sists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK. The module actsas a single master device, e.g. the clock I2CCLK is driven by the module. I2CDAT is a bi-direc-tional line. Each device connected to the bus is software addressable by a unique 7-bit ad-dress, 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 onrequest of the module.The I2C interface can be powered via the V180 line of EHS6. If connected to the V180 line, theI2C interface will properly shut down when the module enters the Power Down mode.Note: Good care should be taken when creating the PCB layout of the host application: Thetraces of I2CCLK and I2CDAT should be equal in length and as short as possible.2.1.8 SPI InterfaceFour EHS6 GPIO interface lines can be configured as Serial Peripheral Interface (SPI). TheSPI is a synchronous serial interface for control and data transfer between EHS6 and the ex-ternal application. Only one application can be connected to the SPI and the interface supportsonly master mode. The transmission rates are up to 26Mbit/s. The SPI interface comprises thetwo data lines MOSI and MISO, the clock line SPI_CLK a well as the chip select line SPI_CS.2.1.9 HSIC InterfaceThe (USB) High Speed Inter Chip Interface can be used between the module and an external application processor and is compliant to the High Speed USB 2.0 interface with 480Mbit/s. The maximum distance between module processor and external application processor should not exceed 100mm.The HSIC interface comprises 6 lines:• Two signal lines (strobe - HSIC_STRB - and data - HSIC_DATA) are used in a source syn-chronous serial interface with a 240MHz clock to provide a 480Mbps USB interface. The HSIC_STRB and HSIC_DATA lines are high-speed signals and should be routed as50Ohm impedance traces. The trace length of these signals should be balanced to mini-mize timing skew and no longer as 100mm.• Four signal lines for Link Power Management (LPM). For further power reduction, the USBHSIC interface supports LPM according to the USB 2.0 standard. The LPM defines powermanagement states and mechanisms to affect state changes that are used by theAP_WAKEUP and CP_WAKEUP signal lines to efficiently manage bus and system power.To take advantage of the LPM feature, two further signals are needed to support powermanagement state transitions - the SUSPEND and HOST_ACTIVE signals.

The PWM interface lines can be used, for example, to connect buzz-ers. The PWM1 line is shared with GPIO7 and the PWM2 line is shared with GPIO6 (for GPIOssee Section 2.1.6). GPIO and PWM functionality are mutually exclusive.2.1.11 Pulse CounterThe GPIO8 line can be configured as pulse counter line COUNTER. The pulse counter inter-face can be used, for example, as a clock (for GPIOs see Section 2.1.6).2.1.12 Status LEDThe GPIO5 interface line can be configured to drive a status LED that indicates different oper-ating modes of the module (for GPIOs see Section 2.1.6). GPIO and LED functionality are mu-tually exclusive.2.1.13 Fast ShutdownThe GPIO4 interface line can be configured as fast shutdown signal line FST_SHDN. The con-figured FST_SHDN line is an active low control signal and must be applied for at least 10ms. If unused this line can be left open because of a configured internal pull-up resistor.

EHS6 Hardware Interface Overview2.2 RF Antenna Interface21EHS6_HIO_v01.441 Page 18 of 38 2013-07-11Confidential / Preliminary2.2 RF Antenna InterfaceThe RF interface has an impedance of 50. EHS6 is capable of sustaining a total mismatch at the antenna line without any damage, even when transmitting at maximum RF power.The external antenna must be matched properly to achieve best performance regarding radi-ated power, modulation accuracy and harmonic suppression. Antenna matching networks are not included on the EHS6 module and should be placed in the host application if the antenna does not have an impedance of 50.Regarding the return loss EHS6 provides the following values in the active band:Table 3: Return loss in the active bandState of module Return loss of module Recommended return loss of applicationReceive > 8dB > 12dBTransmit not applicable > 12dB

EHS6 Hardware Interface Overview2.2 RF Antenna Interface21EHS6_HIO_v01.441 Page 19 of 38 2013-07-11Confidential / Preliminary2.2.1 Antenna InstallationThe antenna is connected by soldering the antenna pad (RF_OUT, i.e., pad #59) and its neigh-boring ground pads (GND, i.e., pads #58 and #60) directly to the application’s PCB. The anten-na pad is the antenna reference point (ARP) for EHS6. All RF data specified throughout this document is related to the ARP.The distance between the antenna RF_OUT pad (#59) and its neighboring GND pads (#58, #60) has been optimized for best possible impedance. On the application PCB, special atten-tion should be paid to these 3 pads, in order to prevent mismatch.The wiring of the antenna connection line, starting from the antenna pad to the application an-tenna should result in a 50 line impedance. Line width and distance to the GND plane needs to be optimized with regard to the PCB’s layer stack. To prevent receiver desensitization due to interferences generated by fast transients like high speed clocks on the application PCB, it is recommended to realize the antenna connection line using embedded Stripline rather than Micro-Stripline technology. For type approval purposes, the use of a 50 coaxial antenna connector (U.FL-R-SMT) might be necessary. In this case the U.FL-R-SMT connector should be placed as close as possible to EHS6‘s antenna pad.

EHS6 Hardware Interface Overview2.3 Sample Application21EHS6_HIO_v01.441 Page 20 of 38 2013-07-11Confidential / Preliminary2.3 Sample ApplicationFigure 6 shows a typical example of how to integrate a EHS6 module with an application. Us-age of the various host interfaces depends on the desired features of the application.Because of the very low power consumption design, current flowing from any other source intothe module circuit must be avoided, for example reverse current from high state external controllines. Therefore, the controlling application must be designed to prevent reverse current flow.Otherwise there is the risk of undefined states of the module during startup and shutdown oreven of damaging the module.Because of the high RF field density inside the module, it cannot be guaranteed that no selfinterference might occur, depending on frequency and the applications grounding concept. ex-cluded that in some applications dependant on the grounding concept of the customer. The po-tential interferers may be minimized by placing small capacitors (47pF) at suspected lines (e.g.RXD0, RXT0, VDDLP, and ON). While developing SMT applications it is strongly recommended to provide test pointsfor certain signals resp. lines to and from the module - for debug and/or test purposes.The SMT application should allow for an easy access to these signals. For details onhow to implement test points see [3].The EMC measures are best practice recommendations. In fact, an adequate EMC strategy foran individual application is very much determined by the overall layout and, especially, the po-sition of components. For example, mounting the internal acoustic transducers directly on thePCB eliminates the need to use the ferrite beads shown in the sample schematic. Please note that EHS6 is not intended for use with cables longer than 3m.DisclaimerNo warranty, either stated or implied, is provided on the sample schematic diagram shown inFigure 6 and the information detailed in this section. As functionality and compliance with na-tional regulations depend to a great amount on the used electronic components and the indi-vidual application layout manufacturers are required to ensure adequate design and operatingsafeguards for their products using EHS6 modules.

Only a voltage regulator is active for powering the RTC. Software is not active. Interfaces are not accessible. Operat-ing voltage (connected to BATT+) remains applied.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 AT command (see [1]).

EHS6 Hardware Interface Overview3.2 Power Supply23EHS6_HIO_v01.441 Page 23 of 38 2013-07-11Confidential / Preliminary3.2 Power SupplyEHS6 needs to be connected to a power supply at the SMT application interface (2 lines each BATT+ and GND). The power supply of EHS6 has to be a single voltage source at BATT+. It must be able to pro-vide 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 baseband using low drop linear voltage regulators anda DC-DC step down switching regulator.• Switches the module's power voltages for the power-up and -down procedures.• SIM switch to provide SIM power supply.

EHS6 Hardware Interface Overview6.4 Safety Precaution Notes36EHS6_HIO_v01.441 Page 36 of 38 2013-07-11Confidential / Preliminary6.4 Safety Precaution NotesThe following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating EHS6. 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. Fail-ure to comply with these precautions violates safety standards of design, manufacture and in-tended use of the product. Cinterion Wireless Modules 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 guide-lines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hear-ing 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 manufac-turer 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 can-not 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 elec-trical 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 driv-ing 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 opera-tion can constitute a safety hazard.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 com-munications, 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 termi-nal or mobile.
