2 SOM-4450 User's Manual
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 CS5530A display controller (LCD and CRT display support) allows
sharp and clear LCD screen resolutions up to 1024 x 768 and CRT
resolutions up to 1280 x 1024 @ 16 colors. Combined with 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. The small size (95 mm x 114 mm) and use of four 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.
