VIPER-400-M64-F32

Arcom VIPER-400-M64-F32 PC/104 CPU Board | with Embedded 400MHz PXA255 XScale Microprocessor

The VIPER is an ultra low power PC/104 compatible single board computer based on the 400MHz PXA255 XScale RISC processor. The PXA255 is an implementation of the Intel XScale microarchitecture combined with a comprehensive set of integrated peripherals including, a flat panel graphics controller, DMA controller, interrupt controller, real time clock and multiple serial ports. The VIPER board offers a long list of features making it ideal for power sensitive embedded communications and multimedia applications. The board has been designed to take advantage of the power saving modes of the PXA255 RISC processor and other onboard peripherals to achieve an incredible 1.9W maximum power consumption. The VIPER also supports a very low power standby mode.
