Introduction
Mobile computing, I/O Intensive SOM
SOM-A2709 series System On Module (SOM) integrates the Marvell XScale PXA270 ultra low power SoC and I/O solution chips together with Windows CE OS support. SOM-A2709 supports rich I/O such as CF/PCMCIA, SD, USB, LAN, multi-COMs, LCD and audio. SOM-A2709 is designed for portable/handheld applications, it supports deep sleep mode and CPU power Speedstep mechanism for power saving and better power management.
Design-in Package ensures efficent evaluation/implementation
The Design-in Package not only includes all the necessary H/W boards, fixtures and LCD related cables, but also includes the Advantech-customized API, utility & reference codes. And of course, it includes all design related documentation including, a white paper for detailed technical know-how. Three supporting mechanisms are included in the Design-in Package: Reference Kit: Includes the Advantech reference Customer Solution Board (CSB) and all documentation relating to CSB design and manufacture. ex : BOM, placement, gerber file, layout etc. file. LCD Kit: Includes the LCD, inverter, T/S and related cables. All goods are pre-verified and supported in Advantech's reference S/W package. Design-in Zone: The web portal for customers to download design-related documentation, SOPs and sample code, also provides end-to-end technical support. (http://risc-designin. advantech.com.tw/)

Notes: * - CPU will spend more resources handling LCD-output at 800 x 600 resolution which will impact other I/O performance. If customers choose 800 x 600 resolution, they need to double check the whole platform performance first. ** - Different CSB design and peripehral connections will cause different power consumption. The value is only for reference.
