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
