Chapter 1: Overview
Description
The XE–800 is a Single Board Computer (SBC) in the EPIC™ form factor. It is
intended for higher-performance, low-power embedded control applications. The
XE–800 SBC integrates serial communications, IDE hard disk port, CompactFlash
socket, digital I/O, six USB ports, keyboard and mouse port, and video. The XE–800
SBC can be used in a stand-alone mode or expanded through a PC/104 or PC/104
Plus
interface.
The XE–800 SBC comes with a BIOS loaded on a flash device for easy updates. It is
fully compatible with most popular operating systems.
XE–800 SBC major hardware features
CPU
The CPU is a high-performance, low-power AMD Geode GX1 processor with a clock
speed of 300 MHz. It uses the CS5530A companion chip for some of the peripherals.
The XE–800 SBC has an ISA bus speed of 8.33 MHz.
SDRAM
The memory socket can accept up to 256 MB capacity SO-DIMM modules.
On-board flash
On board is a 512 KB SMT boot flash that contains the BIOS.
CompactFlash socket
The CompactFlash socket accepts a Type I or Type II 3V CompactFlash card. The
CompactFlash appears as an IDE device to the system. It is implemented with an
ATA-4 compliant IDE controller, and appears in Setup as the Primary IDE device.
Hard disk and IDE port
The XE–800 has two ATA-4 compliant IDE controllers. The primary channel is
dedicated to the CompactFlash. The secondary channel supports two additional
IDE devices through a 2 mm, 44-pin connector. This connector supplies power to
the devices. Octagon Systems has a 44-pin to 40-pin Hard Drive Adapter cable
(part #4080 or #6246) to connect IDE devices with a 40-pin interface.
