PREFACE SCOPE OF THIS MANUAL 1.1 This manual introduces the g20 Developer's Kit, and describes the technical details required by the data terminal equipment
(DTE) team to successfully integrate the Motorola g20 cellular engine into an original equipment manufacturer (OEM) wireless host device. With the help of this manual, the DTE team can use the Developer's Kit to conduct a full series of test and evaluation procedures on the g20, as well as perform application development. We at Motorola want to make this guide as helpful as possible. Keep us informed of your comments and suggestions for improvements. You can reach us by email: GSM support-BSH015@email.mot.com. 1.2 WHO SHOULD USE THIS MANUAL This manual is intended for all members of the DTE OEM integration team who will use the g20 Developers Kit, including representatives from hardware, software and RF engineering disciplines. DISCLAIMER 1.3 This guide provides advice and guidelines to OEM teams. Responsibility regarding how the information is used lies entirely with the OEM. Statements indicating support provided by, or offered by, Motorola are subject to change at any time. Motorola reserves the right to make any changes to this manual. REGULATORY REQUIREMENTS 1.4 The Federal Communications Commission (FCC) requires application for certification of digital devices in accordance with CFR Title 47, Part 2 and Part 15. This includes Electromagnetic Energy Exposure (EME) testing. As the g20 modem is not a standalone transceiver but is an integrated module, the g20 cannot be tested by itself for EME certification. It is, however, the integrators responsibility to have the completed device tested for EME certification. REGULATORY STATEMENT 1.5 The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating the g20 module. 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 prod-
uct. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Motorola assumes no liability for customer failure to comply with these precautions. 1. The g20 must be operated at the voltages described in the technical documentation. 2. The g20 must not be mechanically nor electrically changed. Use of connectors should follow the guidance of the technical documentation. 3. The g20 is designed the meet the EMC requirements of ETS 300 342. 98-08901C64-O 1 Preface 4. When integrating the g20 into a system, Motorola recommends testing the system to ETS300342-1. 5. The g20 meets the safety requirements of EN60950. 6. Systems using the g20 are subject to mandatory EMC testing under directive 89/336/EEC (see item 3 above). Other directives, such as the LVD directive 73/23/EE, may also apply to a system using the g20 module. 1.6 SAFETY 1.6.1 User Operation Do not operate your telephone when a person is within eight inches (20 centimeters) of the antenna. A person or object within eight inches (20 centimeters) of the antenna could impair call quality and may cause the phone to operate at a higher power level than necessary, as well as expose that person to RF energy in excess of that established by the FCC RF Exposure Guidelines. IMPORTANT: The telephone must be installed in a manner that provides a minimum separation distance of 20 cm or more between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting devices. IMPORTANT: To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile transmitters, the requirements described in the section that follows must be met. 1.6.2 Antenna Installation
A minimum separation distance of 20 cm must be maintained between the antenna and all persons.
The effective radiated power of the transmitter must be less than 1.5 Watts ERP (2.45 Watts or 33.9 dBm EIRP). This requires that the combination of antenna gain and feed line loss does not exceed 11 dBi.

RS232
USB
SPI The RS232 and USB ports are multiplexed within the g20, and therefore cannot be operated simultaneously. Their default connection is RS232. The SPI interface is used for debugging. Each of these serial interfaces is described in the sections that follow. 3.2.1 RS232 The RS232 serial port is the primary interface to the g20 UUT via the J350 connector. This port is denoted by the RS232-1 marking beside the 9-pin, D-type connector. The UUT RS232 signals are active-low CMOS-level signals (0-2.7 V), which are converted by the Developer Board to standard RS232 levels for PC communications. Table 2.

The same power source is used for the UUT and the board peripherals. The Developer Board includes three jumpers for controlling the power supply:
P202: AC adapter or battery power source selection
P201: Connects/disconnects the Developer Board peripherals from the power supply
P200: Connects/disconnects the g20 from the power supply Each power supply option is described in the sections that follow. 3.4.1 DC Power Source Operation When using a DC power supply, the power source is applied to connectors J201 (VCC) and J200 (Ground). The DC voltage applied through this connection should not exceed the recommended operational limits of 3V-4.2V. In all cases, the DC source input is protected from over voltage and reverse polarity, and includes a 2.5A protective fuse. The supplied DC input connectors must be attached to the Developer Board in order to use the DC power source. The two connectors should be screwed into their appropriate positions (J201, labeled VCC, and J200, labeled GND). Use the red connec-
tor for VCC and the black one for GND. Connect the DC power source to these connectors using banana plugs, alligator clamps or wire. It is recommended to remove jumper P202 when using the DC power source. In any case, the DC power source should not be used when other sources are connected.

The audio interface contains a hands-free speaker and micro-
phone, a headset, and an alert speaker. 3.8.1 Speaker The differential speaker interface is designed as a car-kit hands-free speaker. The Developer Board uses an audio amplifier to amplify the speaker audio output to desired levels. The speaker connector (J430) is labeled SPEAKER. The speaker output is 8 ohms matched. Table 15.

tor (J440) includes a speaker, microphone and a detection signal. The speaker and microphone signals are directly connected to the g20 audio signals. The purpose of the detection circuit is to switch the g20 headset audio paths on and off, whenever a headset connection is detected. Headset detection is made whenever a headset plug is inserted into the jack. This action disables the g20 microphone and speaker, and routes the audio signals to the headset. Table 18.

Active-low Active-high Not active 3.9.2 Entertainment Mute The Developer Board includes an entertainment-mute logic circuit that is responsible for muting a car radio whenever the phone is in use (for example, incoming calls, dialing, and so on). The entertainment-mute logic circuit includes an ENABLE input that is both a g20 signal and an open-collector MUTE output. This circuit is connected to jumper P130 for host systems. The entertainment-mute operation is not currently supported by the g20. Note 3.9.3 LEDs Logic and Control The Developer Board includes LED indicators for critical signals. A 3.0V regulator powers the LEDs, and an on/off switch controls their operation. The switch is located in the S100 switch array, and is labeled LED. Turning the switch on and off enables or disables all LED activity, respectively. The Developer Board power LED and the g20 on/off LED are always active and cannot be disabled. 3.9.4 ADC Test Logic The g20 has two ADC pins. The g20 charger and temperature monitor currently occupy these pins. The Developer Board includes optional resistors for ADC testing. These resistors, two for each ADC signal, can be used to set a specific voltage across the ADC signal. 24 98-08901C64-O The G20 has a 47K-ohm internal pull-up resistor at each ADC input, as shown in Figure 5. Developer Board and Interfaces Description Figure 5. ADC Test Logic 3.9.5 Ignition The Developer Board contains an on/off switch that is connected to the g20 UUT ignition circuit. The switch is located in the S100 switch array, and is labeled IGN. Turning the switch on applies the UUT supply on the Ignition input pin. 3.9.6 Wakeup The Developer Board includes a wakeup switch that toggles the g20 WAKEUP_IN_N signal. The switch is located in the S100 switch array, and is labeled WAKEUP. 3.9.7 AC Adapter Detection Circuit The g20 charger module includes a detection logic circuit for detecting charger presence and type. The detection circuit is inter-
nal to the g20 module. However, the Developer Board does contain the necessary routing from the g20 UUT to the AC adapter connector. Two g20 signals are used for this detection:
AD1: ADC signal for charger type detection
CHRG_SW: Charger rate control These detection signals are present to provide compatibility with the phone. They may be removed in future versions. 3.10 ANTENNA CONFIGURATION An antenna (internal or external) must be connected to the Developer Board for adequate GSM reception. You can connect the g20 to either the on-board internal antenna or to an external antenna. Two RF connectors on the Developer Board, labeled INT ANT and EXT ANT, are used for this purpose. The EXT ANT connector has an internal extension cable with MMCX termina-
tion, which must be connected to the g20 RF connector. The INT ANT connector is an on-board connection to the Developer Board internal antenna. When using the internal antenna option, the additional RF cable supplied in the Developers Kit must be connected between the EXT ANT and INT ANT connectors. When using the external antenna option, an external antenna or antenna application must be connected to the EXT OUT connector. (The connection cable is not included.) 98-08901C64-O 25 Developer Board and Interfaces Description 3.11 TEST POINTS Table 22 describes the available test points on the Developer Board. Table 22.

INTRODUCTION 2.1 GENERAL DESCRIPTION The g20 is Motorolas newest family of embedded cellular products. Motorola continues its tradition of excellence by introducing 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 to transfer voice or data information. Thus, it significantly enhances the systems 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 fast and easy integration with OEM user products. It significantly shortens the development process for OEM developers, thanks to its wide range of built-in applications, and minimizes the products time to market. The g20 module is ideally suited for the automotive, telemetry, security, insurance and EPOS industries, for delivery and handheld terminals, and for PDA markets. 2.2 TERMS AND ABBREVIATIONS This section provides definitions for terms and acronyms used in this document.

Power supply design g20 current consumption
Turning the unit on/off
Sleep mode options 3.2.1 Power Supply Design The 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 power consumption, 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. 98-08901C64-O 13
Hardware Description
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 to establish a call.
The VCC line typically drops during TX periods. TX TX TX Transmit Periods VCC Figure 6. VCC Signal During TX Periods To minimize the , it is recommended to use lines that are as short as possible, and to place a 1000uF capacitor (or the maximum possible) 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. The power supply should be able to drive at least 2.5 A. Note 3.2.1.1 Power Supply RF Filtering It 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). MUST ALL THESE CAPACITORS BE USED IN PARALLEL? OR SOME COMBINATION?
3.2.2 G20 Current Consumption In order to design the power supply correctly and to calculate the battery life, you should take into account the current consumption of the g20 when operating in different modes. Table 4. g20 Current Consumption Mode Current Consumption (mA RMS) g20 in Sleep mode (camped and Sleep-mode enabled)
< 2.5 mA, RMS @ DRX9, Typical 2.2 mA

@ Power level #19, Typical 135 mA DRX2/9 is the rate used by the base station to query the mobile station. The network operator sets this parameter. Note 3.2.3 Turning the Unit On/Off Two different mechanisms are available to turn the g20 on and off:
On/Off signal (Pin 53) Ignition line (Pin 51) On/Off Signal 3.2.3.1 After power is applied to the g20, the on/off signal is pulled high to the VCC by a 200k resistor. To turn the g20 on, the on/off signal should be pulled low for a minimum of 700 ms. After the g20 is turned on, the line should be pulled low for a minimum of 1.1 seconds to turn it off. The unit can be turned off only if at least seven seconds have elapsed since turning it on. Figure 7 shows the timing diagram for the on/off signal. T1 T2 T3 Figure 7. On/Off Signal Timing Diagram In Figure 7, the following timing requirements apply:
T1 minimum = 0.7 seconds.
T2 minimum = 7 seconds.
T3 minimum = 1.1 seconds. 98-08901C64-O 15
Hardware Description 3.2.3.2 Ignition Line When the g20 ignition line is held at a high level, the g20 is turned on. When this line is pulled low, the g20 is turned off. In order to protect the line from voltage bounces, the g20 is tuned off only if the line is held low for at least 500 ms. The high input to the ignition line must be greater than 2.75 V. The line can tolerate up to 40 V. After the g20 is turned on, the application should wait for DSR before sending data to the g20. The DSR becomes active low eight seconds after the start of T1, or after the ignition line is pulled high. DSR is only valid with UART, and is not valid with USB. 3.2.4 Sleep Mode Options This 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 DTE to be awakened by the g20 when the g20 wants to communicate with it. 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.
The DTE uses CTS to send data only when the g20 is awake. The DTE waits when the g20 is in Sleep mode.
The DTE should drop RTS during the sleep period in order to prevent the loss of data sent by the g20. Figure 8. CTS Sleep Mode Timing 16 98-08901C64-O 3.2.4.2 DCE/DTE Connectivity Figure 9 shows DCE/DTE connectivity:
Hardware Description Figure 9. DCE/DTE Connectivity Waking Up the DCE:
The following apply when waking up the DCE:
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 start sending the data.
While the DTE is sending data, the wake-up line should remain low, so that the g20 does not enter Sleep mode. DTE TXD Wake up In line 30 ms 30 ms 30 ms Figure 10. Waking Up the g20 when the DTE Wants to Send Data Waking 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 S10x in Figure 11. 98-08901C64-O 17 Hardware Description
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. RXD Wake up Out line S10x ms S10x ms S10x ms Figure 11. Waking Up the DTE when the g20 Wants to Send Data 3.3 COMMUNICATION INTERFACES This section describes the following four interfaces that are available in the g20:
RS232
USB
SIM
SPI 3.3.1 RS232 The following apply when using the RS2332 interface of the g20:
The g20 supports full hard-
ware flow control (9 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 12. Figure 12. g20 RS232 Interface 18 98-08901C64-O Hardware Description 3.3.1.1 RS232 Levels RS232 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 uA A buffer is required whenever DTE levels do not match g20 levels. Note 3.3.1.2 RS232 Connection Figure 13 shows an RS232 connection diagram:

The g20 can use both UART and USB connectors, but cannot use them both simultaneously.
When USB is detected (by sensing the USB VBUS signal), the UART is disconnected from the g20 main processor pins and USB functionality is added instead.
The DTE should unload the RS232 lines when USB is used in order for the USB to function properly.
RS232 signals are routed directly from the main processor to the connector. In g20 models without a USB driver (F3001and F3002 models), RS232 signals can be used to connect an external USB driver. Note 98-08901C64-O 19 Hardware Description 3.3.2 USB The following apply for g20 USB connections:
The g20 can use a USB port to communicate with a DTE device.
The USB port is also used to load software into the g20. It is recommended to include connectivity to this port in the user application.
The g20 supports USB1.1 at a baud rate of 12 Mbps.
The g20 supports two basic types, one with a USB driver (models F3003 and F3004), and one with the USB driver removed
(models F3001 and F3002). 3.3.2.1 USB Connection Figure 14 shows g20 connection for g20 models with a USB driver:

When USB VBUS is applied, the g20 detects it and switches the main processor to USB mode. The DTE UART loads the USB driver/main processor lines. Therefore, the UART should be kept in tri-state. Note 20 98-08901C64-O Figure 15 shows g20 USB connection for g20 models without a USB driver, using an external USB driver connection. The circuit shown in this figure can be used by the user application in cases where a USB driver is needed. Hardware Description Figure 15. g20 USB Connection for g20 Models without a USB Driver 3.3.3 SIM The g20 includes a SIM card driver, however, it does not contain a SIM socket. SIM signals are routed to the interface connector and include all the functionality required for SIM card operation. 3.3.3.1 SIM Connection Figure 16 shows a g20 SIM connection:

G20 Figure 16. g20 SIM Connection 98-08901C64-O 21 Hardware Description The following apply for g20 SIM connections:
The g20 passes all SIM ETSI tests when an external socket is connected to the g20 with lines shorter than 10 cm.
Longer connections require SIM testing to be performed in the user application.
The g20 can work with 1.8 V or 3 V SIM cards.
The g20 provides ESD protection for the SIM lines (6.8V Zener diodes with low capacitance), and for 1uF capacitors to the SIM VCC.
The SIM_PD (SIM Present Detect) signal is active when it is pulled low. 3.3.4 SPI The SPI is a standard microprocessor bus used as a g20 debugging port. This port activates a debug option that enables logs to be taken from the g20 while it is operating. It is recommended that this bus be accessible in the user application. In the g20 Developers Kit, the SPI is driven to an SPI/RS232 interface. The SPI is then converted and uses the RS232 port for debugging. In the g20 Developers Kit, the SPI bus is converted to an RS232 protocol using a special interface circuit. It then uses the standard RS232 port for debugging. Table 5 shows the pins available on the SPI bus. 3.3.4.1 SPI Connection Table 5. SPI Pinout Pin #

Each of these functions is described in the sections that follow. 3.3.5.1 Transmit Enable This pin indicates when the g20 is transmitting RF in the antenna. Figure 17. TX_EN Transmission 22 98-08901C64-O 3.3.5.2 Antenna Detect This pin indicates whether or not the antenna is inserted. This option was requested by a specific customer and was prepared specifically for their board layout. Thus, this option is not supported by the basic g20 models. The antenna-detect circuit detects whether the impedance of the antenna is 100 K or lower. The antenna must have a resistance to ground of less than 100 K. in order to be detected. Hardware Description Figure 18. Antenna-detect Circuit 3.3.5.3 GPRS-detect Coverage Indication This pin indicates whether or not the g20 is located in an area with GPRS network coverage. This pin can be used to indicate the GPRS coverage status before GPRS section activation has occurred, or before a switch to circuit-switched data is made. No GPRS Coverage GPRS Coverage Figure 19. GPRS-detect Coverage Indication 3.3.5.4 Entertainment Mute This pin is reserved for future use. It will be dedicated to automotive applications in which there is a need to mute the entertain-
ment radio when there is a cellular call. 3.4 AUDIO INTERFACES The g20 has an analog audio interface and a digital audio interface. Both of these interfaces are described in the sections that follow. 3.4.1 Analog Audio Interfaces The g20 supports microphone input, headset microphone input, differential speaker output, and a differential alert speaker. 3.4.1.1 Analog Input The g20 has two analog inputs that are referenced to the microphone ground (pin 59):
Headset microphone: Pin 57 is the headset microphone input. Input to this line can be directly from a headset microphone. In order for the headset microphone to be active, the headset interrupt signal (pin 55) must be pulled low. The maximum input to the g20 headset microphone before there is a distortion of the signal in the network is 12 mV RMS.
Hands-free microphone: Pin 61 is the microphone input to the g20. The microphone is active when the headset interrupt signal is not pulled low. The maximum input to the g20 microphone before there is a distortion of the signal in the network is 32 mV RMS. 98-08901C64-O 23 Hardware Description 3.4.1.2 Analog Output The 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 the speaker lines.
Alert: The g20 supports a direct connection for an alert transducer, in order to build a handset from the g20. All the sounds that are transmitted to the alert can be routed to the speaker using the appropriate AT command. Table 6 shows the SPKR_N output in headset mode for different network signal levels when the g20 is set to the maximum volume level and the headset interrupt is pulled low. Table 6.

The audio input to the g20 should be referenced to the MIC_GND line of the g20.
The microphone bias of the g20 for both the microphone and headset is 2.2 V. If a microphone with a different voltage is used, 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 be used.
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 Interface The 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. The 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 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 the host. 98-08901C64-O 27
Hardware Description 3.5 ANTENNA The 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 3:1 The antenna should meet this requirement. 3.5.1 Antenna Performance Recommendations Table 12 lists the performance recommendations for the g20 antenna. Table 12. Antenna Performance Recommendations Frequencies:

The software interface is designed to work with a charging IC from National Semiconductor, model LM3652. Refer to the schematics chapter in the g20 Developers Kit for more details about the design of the charging circuitry. 3.7 DISPLAY INTERFACE The g20 supports a four-level gray-scale display with 96 x 65 pixels. The following five lines should be connected to the display:
LCD_CS
LCD_RS
LCD_DATA
LCD_CLK
RESET_N Use the BL_SINK line for backlighting (display and keypad) when using the display. The backlight sink can provide current up to 100 mA, and can be used as an open drain output for more than 100 mA. 28 98-08901C64-O Hardware Description 3.8 ESD PROTECTION In general, the g20 does not include embedded ESD protection circuits. This type of protection should be implemented in the customer 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. 98-08901C64-O 29

INTRODUCTION GENERAL DESCRIPTION 2.1 The g20 is Motorolas newest family of embedded cellular products. Motorola continues its tradition of excellence by introducing 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 to transfer voice or data information. Thus, it significantly enhances the systems 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 fast and easy integration with OEM user products. It significantly shortens the development process for OEM developers, thanks to its wide range of built-in applications, and minimizes the products time to market. The g20 module is ideally suited for the automotive, telemetry, security, insurance and EPOS industries, for delivery and handheld terminals, and for PDA markets.

FCC DOC PTCRB R&TTE EMC GCF REGULATORY REQUIREMENTS 2.6 The Federal Communications Commission (FEC) requires application for certification of digital devices in accordance with CFR Title 47, Part 2 and Part 15. This includes Electromagnetic Energy Exposure (EME) testing. As the g20 modem is not a standalone transceiver but is an integrated module, the g20 cannot be tested by itself for EME certification. It is, however, the integrators responsibility to have the completed device tested for EME certification. REGULATORY STATEMENT 2.7 The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating the g20 module. 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 prod-
uct. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Motorola assumes no liability for customer failure to comply with these precautions. 13. The g20 must be operated at the voltages described in the technical documentation. 14. The g20 must not be mechanically nor electrically changed. Use of connectors should follow the guidance of the technical documentation. 15. The g20 is designed the meet the EMC requirements of ETS 300 342. 16. When integrating the g20 into a system, Motorola recommends testing the system to ETS300342-1. 17. The g20 meets the safety requirements of EN60950. 18. Systems using the g20 are subject to mandatory EMC testing under directive 89/336/EEC (see item 3 above). Other directives, such as the LVD directive 73/23/EE, may also apply to a system using the g20 module. 98-08901C66-G 11 2.8 SAFETY PRECAUTIONS 2.8.1 User Operation Do not operate your unit when a person is within 8 inches (20 centimeters) of the antenna. A person or object within 8 inches
(20 centimeters) of the antenna could impair call quality and may cause the phone to operate at a higher power level than neces-
sary. IMPORTANT: The unit must be installed in a manner that provides a minimum separation distance of 20 cm or more between the antenna and persons to satisfy FCC RF exposure requirements for mobile transmitting devices. IMPORTANT: To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile transmitters, the following requirements must be met:
2.8.2 Antenna Installation The antenna installation must provide a minimum separation distance of 20 cm from users and nearby persons and must not be co-located or operating in conjunction with any other antenna or transmitter. The combined cable loss and antenna gain must not exceed +9.9 dBi and total system output must not exceed 1.5 W ERP
(Cellular) / 3.0 W EIRP (PCS) to qualify for categorical exclusion requirements of 2.1091. OEM installers must be provided with antenna installation instruction and transmitter operating conditions for satisfying RF exposure compliance. 12 98-08901C66-G 3.

Additional g20 Connectivity 16 98-08901C66-G POWER SUPPLY AND CURRENT CONSUMPTION 3.2 This section describes the following power-related considerations for the g20:
Power supply design g20 current consumption Turning the unit on/off Sleep mode options 3.2.1 Power Supply Design The 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 power consumption, 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 to establish a call. The VCC line typically drops during TX periods. TX TX TX Transmit Periods VCC Figure 5. VCC Signal During TX Periods To minimize the , it is recommended to use lines that are as short as possible, and to place a 1000uF capacitor (or the maximum possible) 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. The power supply should be able to drive at least 2.5 A at 3 V DC. Note Power Supply RF Filtering 3.2.1.1 It 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 following capacitor 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. 98-08901C66-G 17 3.2.2 g20 Current Consumption In order to design the power supply correctly and to calculate the battery life, you should take into account the current consumption of the g20 when operating in different modes. Table 4. g20 Current Consumption Mode Current Consumption (mA RMS) g20 in Sleep mode (camped and Sleep-mode enabled)

On/Off signal (Pin 53) Ignition signal (Pin 51) The g20 power-on and power-off timing may vary slightly, depending on the software version. Note 18 98-08901C66-G On/Off Signal 3.2.3.1 The 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 by an internal 200K 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-off process, which lasts about eight seconds, after which the g20 will shut down. The g20 can be turned off only if at least 10 seconds have elapsed since the last power on. Figure 6 shows the timing diagram for the on/off signal. T1 T2 T3 Figure 6. On/Off Signal Timing Diagram In Figure 6, the following timing requirements apply:
T1 minimum = 800 ms. T2 minimum = 10 seconds. T3 minimum = 2 seconds. Ignition Signal 3.2.3.2 The 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 g20 shuts down. Otherwise, the power-off process may be interrupted or may not complete. 3.2.4 Sleep Mode Options This 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 DTE to be awakened by the g20 when the g20 wants to communicate with it. The g20 will not enter sleep mode if the USB is connected. General 3.2.4.1 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. 98-08901C66-G 19 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. g20 Sleep Periods Awake Sleep Inactive CTS Active Awake Active Sleep Inactive Figure 7.

(DTE) Waking 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 start sending the data. 20 98-08901C66-G While the DTE is sending data, the wake-up line should remain low, so that the g20 does not enter Sleep mode. DTE TXD Wake-up In line 30 ms 30 ms 30 ms Figure 9. Waking Up the g20 when the DTE wants to Send Data Waking 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. RXD Wake-up line Out S102 ms S102 ms S102 ms Figure 10. Waking Up the DTE when the g20 wants to Send Data COMMUNICATION INTERFACES 3.3 This section describes the following four interfaces that are available in the g20:
RS232 USB SIM SPI 98-08901C66-G 21 3.3.1 RS232 The 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. g20

(DTE) Figure 11. g20 RS232 Interface RS232 Levels 3.3.1.1 RS232 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 uA A buffer is required whenever DTE levels do not match g20 levels (not 5V tolerant). Note RS232 Connection 3.3.1.2 As 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 power up. 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 support simultaneous operation. When the g20 is switched off, it is recommended to keep the RS232 signals of the DTE at tri-state or at a low level in order to prevent potential latch-up. Note 22 98-08901C66-G 3.3.2 USB The g20 selects its communication channel, RS232 or USB, depending on the state of the USB_VBUS signal (pin 10) at power up. The g20 operates in USB mode if the USB_VBUS signal is high at power up and remains high during operation. The USB_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 support simultaneous operation When USB is used, the DTE device must unload (meaning disconnect or place in tri-state) the RS232 lines. Otherwise, the USB may 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 user application. The g20 supports USB 1.1 at a baud rate of 12 Mbps.

When USB VBUS is applied, the g20 detects it and switches the main processor to USB mode. The 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. Note 98-08901C66-G 23 3.3.3 SIM The g20 includes a SIM card driver, however, it does not contain a SIM socket. SIM signals are routed to the interface connector and include all the functionality required for SIM card operation. The SIM card socket must be located in the customer application, and connected to the g20 interface connector as described in the following section. SIM Connection 3.3.3.1 Figure 13 shows a g20 SIM connection:
Figure 13. g20 SIM Connection The 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 signal connections 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 proper SIM 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 application and 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 ESD protection. 24 98-08901C66-G 3.3.4 SPI The SPI is a standard microprocessor bus used as a g20 debugging port. This port activates a debug option that enables logs to be taken from the g20 while it is operating. It is recommended that this bus be accessible in the user application. In the g20 Developers Kit, the SPI bus is converted to an RS232 protocol using a special interface circuit. It then uses the standard RS232 port for debugging. Table 5 shows the pins available on the SPI bus. 3.3.4.1 SPI Connection Table 5. SPI Pinout Pin #

Each of these functions is described in the sections that follow. Transmit Enable 3.3.5.1 This pin indicates when the g20 is transmitting RF in the antenna. No RF Transmitted RF Transmission No RF Transmitted Figure 14. TX_EN Transmission GPRS Coverage Indication 3.3.5.2 This pin indicates whether or not the g20 is located in an area with GPRS network coverage. This pin can be used to indicate the GPRS coverage status before GPRS section activation has occurred, or before a switch to circuit-switched data is made. The default operation of this signal is active low, meaning this signal is at 0 when GPRS coverage is available. It is possible to switch the signals polarity to active high using an AT command. Refer to the g20 AT Commands document (9808901C68-O) for the AT commands description. 98-08901C66-G 25 Antenna Detect 3.3.5.3 This pin indicates whether or not the antenna is inserted. This option can be used with antennas with a resistance to ground of less than 100K. The antenna detect circuit detects whether the ohmic resistance of the antenna is 100 Kohm or lower, which is required 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, and exhibits best results when connected back to the g20. A dedicated g20 input signal, pin 37, is available for the antenna detection input. This is to ensure proper operation of the antenna-detect AT command, which enables software indication of the antenna state. Antenna Not Detected Antenna Detected Figure 15. Antenna Detect AUDIO INTERFACES 3.4 The g20 has an analog audio interface and a digital audio interface. Both of these interfaces are described in the sections that follow. 3.4.1 Analog Audio Interfaces The g20 supports microphone input, headset microphone input, differential speaker output, and a differential alert speaker. Analog Input 3.4.1.1 The g20 has two different analog inputs, referenced to the microphone ground (pin 59). The g20 contains an analog amplifier with a default gain of 16dB, which can be adjusted in seven steps between 0 and 31dB using the AT+MMICG command. For more 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 headset microphone. 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 is 32 mvRMS. Analog Output 3.4.1.2 The 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 the speaker lines. Alert: The g20 supports a direct connection for an alert transducer, in order to build a handset from the g20. All the sounds that are transmitted to the alert can be routed to the speaker using the appropriate AT command. 26 98-08901C66-G Table 6 shows the SPKR_N output in headset mode for different network signal levels when the g20 is set to the maximum volume level and the headset interrupt is pulled low.

The audio input to the g20 should be referenced to the MIC_GND line of the g20. The microphone bias of the g20 for both the microphone and headset is 2.2 V. If a microphone with a different voltage is used, 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 be used. The g20 GND should be connected on all four pins, with two mounting screws to the application ground. The digital lines of the application should never be referenced to the MIC_GND. If possible, the RF cable ground from the g20 should be connected to the GND of the g20. 3.4.2 Digital Audio Interface The 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. 30 98-08901C66-G The 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. ANTENNA 3.5 The 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 Recommendations Table 12 lists the performance recommendations for the g20 antenna.

This type of protection should be implemented in the customer 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. 98-08901C66-G 31 4. CONNECTOR PIN ASSIGNMENTS CONNECTORS 4.1 The g20 has two connectors: the g20 interface connector and the g20 RF connector.

Do not apply external voltage on any of the g20 logic signals when the g20 is powered off. The RESET_N output signal (pin 25) is tri-state when the g20 is powered off. It is recommended to place a 10K pull-down resistor on this signal in the customer application to ensure proper logic-level transitions.

Introduce the user to the g20 TESTING A STANDALONE UNIT 6.2 This section describes how to perform a functionality test on a g20 unit. The test is performed in order to:
Explain how to work with the g20 unit Describe how to evaluate basic g20 features The test setup provides a wide platform through which a g20 unit can be evaluated. The specific test procedure described below covers only few of the g20s 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 single computer, which also controls their operation. The test requires knowledge about the operation of the g20 Developers Kit, terminal applications and AT commands. Refer to relevant 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) 98-08901C66-G 45 6.2.1 Test Setup Follow 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 Developers Kit document by doing the following:
Verify that the g20 has adequate reception from the local GSM network. Connect the Developer Boards RS232 port to the computers serial port. 3. Open a terminal application window (such as HyperTerminal) in the computer and configure it to operate with the serial port occupied by the g20. 4. Open a second terminal window and configure it to operate with the serial port occupied by the line modem. To telephone line wall outlet Line Modem
(internal or external) Serial Port Serial Port RS232 Port Computer Developer Board with g20 unit Serial Cable 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 Procedure Follow 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 the modems 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 appropriate window. 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 file created specifically for the test. 6. Send the file through the terminal application, from the g20 or to it, using the terminal applications send/receive file options. 7. When the file transfer is completed, use the "ath" command in any of the terminal windows to terminate the call. This step completes the test. You can now continue to perform additional tests using the same setup, or change the setup as required. 46 98-08901C66-G 7.

Be sure to take appropriate precautionary measures in order to avoid ESD while handling the kit. ESD can damage the Developer Board and/or the g20 module attached to it. 98-08901C67-D 1 1.4.2 User Operation Do not operate your unit when a person is within eight inches (20 centimeters) of the antenna. A person or object within eight inches (20 centimeters) of the antenna could impair call quality and may cause the unit to operate at a higher power level than necessary, as well as expose that person to RF energy in excess of that established by the FCC RF Exposure Guidelines. IMPORTANT: The unit must be installed in a manner that provides a minimum separation distance of eight inches (20 centi-
meters) or more between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting devices. IMPORTANT: To comply with the FCC RF exposure limits and to satisfy the categorical exclusion requirements for mobile transmitters, the requirements described in the following section must be met. 1.4.3 Antenna Installation A minimum separation distance of eight inches (20 centimeters) must be maintained between the antenna and all persons. The effective radiated power of the transmitter must be less than 3.0 Watts ERP (4.9 Watts or 36.9 dBm EIRP). This requires that the combination of antenna gain and feed line loss should not exceed 9.9 dBi.

You can connect the g20 to either the on-board internal antenna or to an external antenna. Two RF connectors on the side of Developer Board, labeled INT ANT and EXT ANT on the cover, are used for setting up the antenna. External Antenna Input Internal Antenna Input Figure 16. Antenna Connectors (external) On the inside of the Developer Board, the EXT ANT connector is connected to the g20 and the INT ANT is connected to the on-board internal antenna. You must perform one of the following:
To use the internal antenna, connect the EXT ANT and INT ANT connectors with the additional RF cable supplied in the Developers Kit. This is the Developer Boards default configuration. It arrives with the EXT ANT and INT ANT already connected. INT ANT Additional RF Cable EXT ANT g20 RF Cable On-board Internal Antenna Figure 17. Antenna Connectors (internal) To use an external antenna, connect an external antenna or antenna application to the EXT ANT connector. (The connection cable is not included.) You must first disconnect the external RF cable from the EXT ANT connector. 98-08901C67-D 25 3.4.5 Option Switches Figure 18 shows the Dip switches provided on the Developer Board, which are located on the S100 component. The following Dip switches are provided:
Figure 18. Option Switches Table 18. Option Switches Reference Description WAKEUP g20 wakeup signal IGN LEDS g20 ignition circuit on/off switch for LEDs 3.4.5.1 Wakeup The WAKEUP switch is connected to the g20s internal wakeup interrupt module through the WAKEUP_IN_N signal. This line should be in the off position to enter Sleep mode and in the on position to wake up. Generally, your application wakes up the g20. In cases where the application is not ready for integration, you can force wakeup of the g20 by turning on this Dip switch. Ignition 3.4.5.2 The IGN switch activates the g20 ignition circuits through the IGN signal. You can use this switch to turn the g20 on and off. LEDs Control 3.4.5.3 The Developer Board includes LED indicators for critical signals. The LED switch enables you to turn off all the LEDs on the Developer Board, for example, to reduce power consumption. The Developer Board power on/off LED and the g20 on/off LED are always active and cannot be disabled. 26 98-08901C67-D 3.4.6 SIM Card The SIM card connector (J100) is external to the g20, but is connected directly to it, similar to an internal SIM. The g20 can accept 1.8V and 3V SIM cards. Table 19. SIM Connector Pinout (J100) Pin 1 2 3 4 5 6 7 8 Description Ground Presence detect Clock Reset VCC Serial data I/O VPP Ground The g20 detects the presence of the SIM card through the SIM_PD signal. This signal is configured in the g20 as active-low. The Developer Board is configured to support the g20's default active-low detection, but can also support active-high detection, if necessary. Use the SIM card detect logic jumper (P110), labeled SIM, to select active-low or active-high SIM card detection configurations. Table 20. SIM Card Detect Logic Jumper (P110) P110 Jumper Position 1 2 3 Selected Mode Active-low Active-high Not active 98-08901C67-D 27 3.4.7 Host Connection An external application may communicate with the g20 through the host connector (J1) and control some or all of the g20's functions. The host connector enables you to integrate the g20 into an application without installing the g20 inside the product. The host connector operates in parallel with the developer board peripherals and enables an external application to share g20 resources with the developer board. You may select any g20 function to control externally, through the host connector, and allow the developer board to control other functions. 70-pin Host Connector g20 70-pin Header Connector g20 70-pin Connector Figure 19. 70-pin Connectors You can connect an external application to the g20 Developer Board using a host interconnect flex cable and connecting it to the host connector (J1). Connect the other end of the cable to the external application. The cable is an optional accessory. All pin numbers and functions of the host connector are identical to those of the g20 UUT (P1) and the g20 diagnostic connector
(P100). For more information on the pins of the host connector, refer to UUT Interface Connector on page 30. The following are guidelines for using the host connector:
When using an external SIM card through the host connector, the developer board SIM card jumper (P110) must be discon-
nected and the SIM card tray should be empty. When using any of the serial communication channels (USB, RS232, SPI) through the host connector, the developer board serial connectors should not be used. When using the IGN or WAKEUP functions through the host connector, the functions should be switched off on the devel-
oper board Dip switches. When using the analog audio channels through the host connector, disconnect all audio devices from the developer board. When using the PCM digital audio through the host connector, it is recommended to place the audio selection jumper (P420) to analog audio mode. When connecting an external application that provides the power to the g20 and the Developer Board, remove any other power sources from the Developer Board. 28 98-08901C67-D 3.5 COMPONENTS AND SPECIFICATIONS 3.5.1 Connectors Description All the Developer Board connectors are marked by their reference number and by a pin-1 indicator.
