2 Introduction

2.1

Product Description

The COMe-cDC2 brings latest 45 nm performance generations of Intel® Atom™ N270 processor with 1.6 GHz and the
Intel® 945GSE and ICH7M chipset to a compact 95 x 95 mm module.
Kontron's new high-efficient power-off state S5 Eco enables ACPI features and lowest power-consumption in soft-off
state – less than 1 mA. Compared to the regular S5 state this means a reduction by at least factor 200! Battery uptime
therefore goes up dramatically.
Like all COM Express® compact modules, it is compatible to the COM Express® basic. Therefore, upgrading existing carrier
boards originally designed for COM Express® basic gets easy and minimizes redesign efforts.

Naming clarification

COM Express® defines a Computer-On-Module, or COM, with all components necessary for a bootable host computer,
packaged as a super component.
» COMe-bXX# modules are Kontron's COM Express® modules in basic form factor (125mm x 95mm), formerly known
as ETXexpress®
» COMe-cXX# modules are Kontron's COM Express® modules in compact form factor (95mm x 95mm), formerly known
as microETXexpress®
» COMe-mXX# modules are Kontron's COM Express® modules in mini form factor (55mm x 84mm), formerly known as
nanoETXexpress
The product names for Kontron COM Express® Computer-on-Modules consist of a short form of the industry standard
(COMe-), the form factor (b=basic, c=compact, m=mini), the capital letters for the CPU and Chipset Codenames (XX) and
the pin-out type (#) followed by the CPU Name.
2.3 Understanding COM Express® Functionality
All Kontron COM Express® basic and compact modules contain two 220pin connectors; each of it has two rows called Row
A & B on primary connector and Row C & D on secondary connector. COM Express® Computer-on-modules feature the
