1 Overview
1.1 Introduction
The Cool LiteRunner-LX800 (CLR-LX800) is a PC/104 board with AMD's Geode™ LX processor and
has a very good performance- power- ratio. The board comprises all peripherals needed for an
embedded PC on a small 3.775" by 4.050" printed circuit board. On the top side it is fully plug-in
compatible with the Cool LiteRunner 2.
The CLR-LX800 integrates a powerful yet efficient AMD Geode™ LX800 processor together with a
CS5536 I/O companion and a Super I/O chip to form a complete PC, with all the standard
peripherals already onboard. There is a graphics controller with VGA and LVDS adapters to connect
different sorts of display terminals. Backlighting is provided for LCD modules too.
Two fast 100/10BaseT Ethernet ports, two RS232/RS422/RS485 serial ports, one RS485/ IrDA serial
port and four USB 2.0 host ports handle the communication with external devices. There are PS/2
connectors for keyboard and mouse as well as a parallel printer port available. An IDE ATA100
adapter allows connection of hard disk or CD drives. Applications that require non-moving storage
can use a plugged compact flash in a mounted socket which is connected to the ATA-controller.
System expansion can easily be realized over PC/104 and I²C bus connectors.
The CLR-LX800 is powered by a 5V-only supply and supports ACPI, advanced power management
and PCI power management. Security critical applications take advantage of the Geode LX
processor, too. It has an on-chip AES 128-bit crypto acceleration block capable of 44 Mbps
throughput on either encryption or decryption. The AES block runs asynchronously to the processor
core and is DMA based.
The CLR-LX800 runs DOS, Windows, Linux and VxWorks operating systems.
