VIPER Technical Manual Introduction

Introduction

The VIPER is an ultra low power, PC/104 compatible, single board computer available in two standard variants:

•VIPER, based on the 400MHz PXA255 XScale processor.

•VIPER-Lite, based on the 200MHz PXA255 XScale processor.

The PXA255 is an implementation of the Intel XScale micro architecture combined with a comprehensive set of integrated peripherals including: a flat panel graphics controller, interrupt controller, real time clock and multiple serial ports. The VIPER board offers a wide range of features making it ideal for power sensitive embedded communications and multimedia applications.

Both of the standard variants are available in two memory configurations, as shown below:
