1.1 Introduction

Advantech's SOM-ETX form factor System On Module provides a

scalable solution that meets customers' advanced CPU and application

development needs. The SOM-4450 incorporates a low power, fanless

GX1-300 MHz processor that has become the embedded integrators'

processor of choice. It uses a NS CS5530A chipset as its VGA/LCD

controller, with single 18 bit LVDS interface and 64-bit graphics engine.

The CS5530Adisplay controller (LCD and CRT display support) allows

sharp and clear LCD screen resolutions up to 1024 x 768 and CRT

resolutionsupto 1280x1024 @16 colors. Combinedwith the CS5530A

system chipset is a RealTek RTL 8139 ethernet chipset. It supports all

functions of an AT-compatible industrial computer. There is one

SODIMM socket that supports 16 MB to 128 MB synchronous

DRAM.Thesmall size(95 mm x114 mm)anduse offour high capacity

connectors based on the proven ETX form factor, allow the SOM-ETX

modules to be easily and securely mounted onto a customized solution

board or our standard SOM-DB4400 development board.

Many gains were made by using the Geode™ GX1 processor. The GX1

processor provides the lowest power consumption combined with

high speed 586 processing power. This GX1 processor also supports

most popular web plug-ins and leverages existing software and

hardware investments. Onboard features include an ethernet interface,

socket for CompactFlash™ card , Enhanced IDE interface capable of

Ultra DMA transfer protocol, one parallel port, two serial ports and a

PS/2 keyboard/mouse interface.
