Developer Board and Interfaces Description10 98-08901C64-O3.2 COMMUNICATIONS INTERFACESThe g20 Developer Board includes three different serial interfaces: •RS232•USB• SPIThe RS232 and USB ports are multiplexed within the g20, and therefore cannot be operated simultaneously. Their defaultconnection is RS232. The SPI interface is used for debugging.Each of these serial interfaces is described in the sections that follow.3.2.1 RS232The RS232 serial port is the primary interface to the g20 UUT via the J350 connector. This port is denoted by the RS232-1marking 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 standardRS232 levels for PC communications.Table 2. RS232-1 Connector Pinout (J350)Pin # Description DTE I/O1 DCD In2RXD In3TXD Out4DTR Out5 Ground6DSR In7RTS Out8CTS In9RI InNoteThe RS232 connector pin names are DTE-oriented.DRAFT 1 (31.3.03)
98-08901C64-O 11Developer Board and Interfaces Description3.2.2 USBThe USB interface operates according to the g20 UUT configuration. The Developer Board has a complete USB transceivercircuit to support USB communications for g20 units that do not include a USB driver of their own. The Developer Board USBinterface can be overridden manually when using a g20 unit that does include its own USB driver interface.The USB jumper (P300) located next to the USB connector selects between the Developer Board USB interface and the UUTUSB interface. By changing the jumper position, the USB_VBUS signal is diverted to the selected driver (in the g20 or on theDeveloper Board) and operates it.3.2.3 SPIThe Developer Board includes a secondary 4-wire RS232 interface, which is connected to the g20 internal SPI bus through theJ500 connector. This interface is used to debug applications. This port is denoted by the RS232-2 label next to the 9-pin D-typeconnector.Table 3. USB Connector Pinout (J3)Pin # Description1VCC2D-3D+4GroundTable 4.

Developer Board and Interfaces Description12 98-08901C64-OOn the Developer Board, the g20 SPI interface is converted to standard RS232 signals for PC communications. The conversionprocess uses the RS232 interface as a second slave on the internal g20 SPI bus, and communicates with it as such. SPI read andwrite operations are performed normally, using the CS and IRQ signals provided by the conversion circuit. The IRQ signal isconnected to a g20 IRQ pin.3.3 CONNECTORS DESCRIPTIONAll the Developer Board connectors are marked by their reference number and by a pin-1 indicator.

Developer Board and Interfaces Description22 98-08901C64-OThe P420 jumper selects the speaker and microphone source, as indicated in Table 17.3.8.4 HeadsetThe headset interface is designed as a portable phone audio interface, and is similar to the headset interface. The headset connec-tor (J440) includes a speaker, microphone and a detection signal. The speaker and microphone signals are directly connected tothe g20 audio signals.The purpose of the detection circuit is to switch the g20 headset audio paths on and off, whenever a headset connection isdetected. Headset detection is made whenever a headset plug is inserted into the jack. This action disables the g20 microphoneand speaker, and routes the audio signals to the headset.Table 17.

Developer Board and Interfaces Description24 98-08901C64-OThe SIM card supports both active-high and active-low detection configurations. Jumper P110 is used to select between theseconfigurations.3.9.2 Entertainment MuteThe Developer Board includes an entertainment-mute logic circuit that is responsible for muting a car radio whenever the phoneis 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.3.9.3 LEDs Logic and ControlThe Developer Board includes LED indicators for critical signals. A 3.0V regulator powers the LEDs, and an on/off switchcontrols their operation. The switch is located in the S100 switch array, and is labeled LED. Turning the switch on and offenables 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 LogicThe g20 has two ADC pins. The g20 charger and temperature monitor currently occupy these pins. The Developer Boardincludes optional resistors for ADC testing. These resistors, two for each ADC signal, can be used to set a specific voltage acrossthe ADC signal.Table 21.

98-08901C64-O 25Developer Board and Interfaces DescriptionThe G20 has a 47K-ohm internal pull-up resistor at each ADC input, as shown in Figure 5.Figure 5. ADC Test Logic3.9.5 IgnitionThe Developer Board contains an on/off switch that is connected to the g20 UUT ignition circuit. The switch is located in theS100 switch array, and is labeled IGN. Turning the switch on applies the UUT supply on the Ignition input pin.3.9.6 WakeupThe Developer Board includes a wakeup switch that toggles the g20 WAKEUP_IN_N signal. The switch is located in the S100switch array, and is labeled WAKEUP. 3.9.7 AC Adapter Detection CircuitThe 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 adapterconnector.Two g20 signals are used for this detection:•AD1: ADC signal for charger type detection•CHRG_SW: Charger rate controlThese detection signals are present to provide compatibility with the phone. They may be removed in future versions.3.10 ANTENNA CONFIGURATIONAn antenna (internal or external) must be connected to the Developer Board for adequate GSM reception. You can connect theg20 to either the on-board internal antenna or to an external antenna. Two RF connectors on the Developer Board, labeled INTANT 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 DeveloperBoard internal antenna.When using the internal antenna option, the additional RF cable supplied in the Developer’s Kit must be connected between theEXT ANT and INT ANT connectors. When using the external antenna option, an external antenna or antenna application mustbe connected to the EXT OUT connector. (The connection cable is not included.) DRAFT 1 (31.3.03)
