The VIPER is an extremely low power PC104 compatible single board computer designed on the 400MHz Marvell® XScale PXA255™ RISC processor. The VIPER board offers a deep list of features making it an ideal solution for power sensitive embedded communications and multimedia applications and platforms.
Power Consumption
The board has been designed to take advantage of the power thrifty modes of the PXA255™ processor and other on-board peripherals to achieve an incredibly low 1.9W maximum power consumption. In addition to the low power consumption, the VIPER supports a very low power standby mode of just 250mW.
Interfaces
The PXA255™ is an implementation of the ARM compliant, Intel XScale microarchitecture used in conjunction with a comprehensive set of integrated peripherals and interfaces including: TFT/STN flat panel graphics controller, onboard soldered SDRAM and resident Flash, 10/100baseTx Ethernet, 5 serial ports, I²C controller, dual USB host controller, USB client, AC97 audio/codec, CompactFlash interface (CF+), and a standard PC/104 bus expansion connector.
