Chapter 1: Introduction The C24 is the newest member of Motorola's embedded cellular modules family. Designed with dual band CDMA operation, embedded GPS receiver, and with 1x Data capabilities, C24 can operate on any CDMA 1x network to provide voice and data communications, and positioning information. The C24 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 C24 is designed as a complete CDMA 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 C24 operation. The C24 control and indication interface extends its capabilities beyond CDMA communications. This includes an A/D and GPIO interface, and a regulated output voltage for supplying external circuits. With these interfaces, the C24 can operate and control external applications and receive feedback from external environment and circuits. The integrated GPS receiver supports autonomous and assisted modes of operation for a reliable and immediate location determination. The location information is provided in NMEA format or by AT commands, which provides the application flexible design. The C24 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 C24 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. December 15, 2008 C24 Module Hardware Description 1

Chapter 1: Introduction
The C24 is the newest member of Motorola's embedded cellular modules family.
Designed with dual band CDMA operation, embedded GPS receiver, and with 1x Data
capabilities, C24 can operate on any CDMA 1x network to provide voice and data
communications, and positioning information.
The C24 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 C24 is designed as a complete CDMA 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 C24 operation.
The C24 control and indication interface extends its capabilities beyond CDMA communications.
This includes an A/D and GPIO interface, and a regulated output voltage for supplying external
