1. INTRODUCTION
The ETX-N270 is a highly integrated computer-on-module (COM) based on the low power, high performance Intel
Atom N270 processor clocked at 1.6GHz. The module provides an SO-DIMM socket for up to 2GB of DDR2
DRAM, and provides interface controllers for high-resolution CRT and LVDS-interfaced displays, 10/100Mbps
Ethernet, SATA and IDE storage devices, USB 2.0, audio, serial, parallel, and PS/2 ports. Additionally, the ETX-
N270 provides a high degree of system expansion flexibility via the presence of both 32-bit PCI and 16-bit ISA
expansion buses on its ETX 3.0 compliant baseboard interface connectors.
