Chapter 1: Introduction - Motorola G24 Developer's Manual

Chapter 1: Introduction

The G24 is the newest member of Motorola's embedded cellular modules family.
Designed with quad band GSM capabilities, which supports all four GSM bands -
850/900/1800/1900 MHz, and with GPRS multislot class 10, G24 can operate on any
GSM/GPRS network to provide voice and data communications.
The G24 is similar to a condensed cellular phone core, which can be integrated into any system or
product that needs to transfer voice or data information over a cellular network. Thus, it
significantly enhances the system's capabilities, transforming it from a standalone, isolated
product to a powerful high-performance system with global communications capabilities.
The G24 is designed as a complete GSM communications solution with all the controls,
interfaces and features to support a broad range of applications:
•
A powerful audio interface
•
A large set of indicators and control signals
•
Several advanced power-saving modes
•
A variety of serial communications solutions.
All these features and interfaces are easily controlled and configured using a versatile AT
command interface that provides full control over the G24 operation.
The G24 control and indication interface extends its capabilities beyond GSM communications.
This includes an A/D and GPIO interface, and a regulated output voltage for supplying external
circuits. With these interfaces, the G24 can operate and control external applications and receive
feedback from external environment and circuits.
The G24 interface design, using a single 70 pin board-to-board connector, through which all
application interfaces are managed, facilitates fast and easy integration. It significantly shortens
the development process, and minimizes the product's time to market.
The G24 is extremely compact in size with a slim mechanical design, which makes it space
saving on the application board and easily fitted into any board design.
The advanced power supply management significantly reduces power consumption to a
necessary minimum and prolongs battery life.
