1.1 Introduction

We are appreciating your purchase of AAEON's Embedded

Technology EXtended (ETX) product –the ETX-821.

Being an ETX compatible module, the ETX-821 was designed

specially to improve the quality and speed of your product

development. It will provide a more compact size and more

flexibility for your various applications.

The features of the ETX-821 are based on the Intel®Ultra Low

Voltage Celeron®M or LV Pentium®Mprocessor combined with

Intel®852/855 (GM/GME) and ICH4 chipsets. It has one 200-pin

SODIMM socket that allows a system memory capacity up to 1GB

with DDR SDRAM module. Hence, the ETX-821 can provide

common PC peripheral functions such as graphics, USB, serial,

parallel ports, keyboard/mouse, Ethernet, and IDE. The baseboard

designer can optimize exactly which and how these functions are

implemented physically.

All of AAEON's ETX modules have a standard form factor and a

standard connector layout that carry a specified set of signals. By

adopting this standardization, the designers can create a single

system of “baseboards” that can accept present and future ETX

modules. The baseboard designer can optimize exactly how each

ETX CPU Module ETX-821

of these functions is implemented physically. Designers can place

connectors precisely where needed for the application on a

baseboard designed to optimally fit a system’s packaging.

AAEON’s ETX system is your stepping-stone to a whole new world

of embedded product development. Once again, thank you for your

purchase of this AAEON product and we trust that your product

development will be swift, sure and successful!
