1. PREFACE
1.1 SCOPE OF THIS MANUAL
This manual introduces the g20 Developer's Kit, and describes the technical details required by the user to successfully integrate
the Motorola g20 cellular engine into an original equipment manufacturer (OEM) wireless host device. With the help of this
manual, the user can utilize 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: n2cshd@motorola.com.
1.2 WHO SHOULD USE THIS MANUAL
This manual is intended for all members of the integration team who are responsible for integrating the g20 into the host appli-
cation, including representatives from hardware, software and RF engineering disciplines.
1.3 DISCLAIMER
This guide provides advice and guidelines to developers. Responsibility regarding how the information is used lies entirely with
the user. 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.
1.4 SAFETY
1.4.1 Precautions
Most Developer Board circuits are not shielded. 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.
![](/img.php?id=575753&img=bge.png)
2 98-08901C67-D
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 may also want to remove the g20 power jumper and then connect an amperometer to the jumper’s two pins to measure the
current through the g20.
3.4.2 Communication Interfaces
The g20 Developer Board includes three serial interfaces:
• RS232
•USB
• Diagnostics
The RS232 and USB ports are multiplexed within the g20, and therefore cannot be operated simultaneously. The default
connection is RS232.
The USB and RS232 is not detected dynamically. The selected serial connection is determined by the USB cable connection at
power up. If the USB cable is connected (and the PC is on), then USB is selected. Otherwise, RS232 is selected.
The Diagnostics RS232 interface is used for debugging.

3.4.2.1 RS232
The 9-pin, D-type RS232-1 serial port (J350) is the primary interface to the g20 UUT. 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.
3.4.2.2 USB
The USB interface connector (J300) is a standard B-type USB device interface. The g20 USB signals are routed directly to this
connector. The Developer Board includes a USB driver circuit, similar to the g20’s internal USB circuit, for reference and
testing purposes only. For proper USB communications, the Developer Board’s USB driver should not be used.

3.4.2.3 Diagnostics
The 9-pin D-type Diagnostics serial port (J500) is connected to the g20 internal SPI bus. This interface is used to debug appli-
cations.
On the Developer Board, the g20 SPI interface is converted to standard RS232 signals for PC communications. The conversion
process uses the RS232 interface as a second slave on the internal g20 SPI bus, and communicates with it as such. SPI read and
write operations are performed normally, using the CS and IRQ signals provided by the conversion circuit. The IRQ signal is
connected to a g20 IRQ pin.

connector (J440), labeled HEADSET, 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.
3.4.3.5 Alert Transducer
The Developer Board includes an on-board transducer, labeled ALERT, for alert audio sounds (LS400). The transducer is
connected directly to the g20 differential alert outputs. The alert transducer sounds the g20 MIDI signals.

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.
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-

3.5.4 MMI
The Developer Board includes a man-machine interface (MMI), complete with display and keypad. The MMI is intended for
initial operation and evaluation of the g20.
The keypad does not function on generic g20 sales models, a special flex should be requested in order to have the keypad func-
tioning.
For more information on MMI connections, refer to the schematics in “Schematics and Placement Diagrams” on page 55.
3.5.5 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:
•CHRG_TYP: 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.
3.5.6 Electrical Specifications
Table 25 describes the electrical specifications of the Developer Board.
* When using DC power supply only.
** Depends on the active peripherals (LEDs, UART, USB, and so on) in use.
