1 Introduction
This document presents general information on CPB904 processor module, the details of its proper
and safe installation, configuration and operation.
1.1 Module
Introduction
CPB904 is an ETX computer-on-module (COM), highly integrated and compact single board
computer for use in systems requiring low power consumption and wide operating temperature
range. All I/O signals as well as full realization of ISA and PCI buses are mapped to four standard
high density, low profile connectors on the bottom side of the module. CPB904 is designed for use
in applications being mounted on an ETX baseboard.
CPB904 is based on low power AMD Geode LX800 CPU and AMD CS5536AC I/O companion.
Dynamic Memory interface supports 64-bit DDR SDRAM via SODIMM socket and soldered 128 or
256 MB memory bank.
All key components including CPU, chipset, memory, and periphery controllers are soldered
on-board providing excellent vibration stability and increased efficiency of protective conformal
coating.
CPB904 offers wide variety of data display capabilities. It allows simultaneous operation of
standard VGA interface, 24-bit LVDS interface, and 18-bit interface for TFT or DSTN LCD panels
connection. In addition TV output is available.
Data storage subsystem is based on single-channel IDE controller, that is able to drive up to two
IDE devices: two external hard drives, CompactFlash card.
For data exchange, CPB904 uses one independent Fast Ethernet port, three COM ports, four USB
2.0 ports, IrDA port, and parallel port combined with FDD and with 17 programmable discrete
input/output lines.
System control and management capabilities of CPB904 include watchdog timer, reserved BIOS,
and possibility to save system configuration and emergency parameters in FRAM chip.
CPB904 is manufactured in three versions: CPB904-01 (256 MB of soldered system memory),
CPB904-02 (512 MB soldered), and CPB904-03 with SODIMM socket for up to 512 MB DDR
SDRAM.
CPB904 is designed for operation within industrial temperature range from –40 C to +85°C.
CPB904 supports wide range of operating systems – Fastwel DOS (MS DOS-compatible),
Windows XP embedded, QNX 4.25 and 6.3x, Linux 2.4, and Windows CE.NET 4.2.
