The VIA VX855 is a low-power, highly integrated all-in-one system processor chip in a small 27mm x 27mm package that addresses key requirements of small form factor, high performance, power sensitive embedded applications. The VIA VX855 is VIA’s first integrated single chip that introduces the advantages of next-generation high definition H.264 and VC-1 video compression algorithms while maintaining a maximum power of only 2.3 watts, delivering the best performance in a small package.

The VIA VX855 integrates a high performance DDR2 memory controller up to 800 MHz, a 400/800 MHz FSB CPU interface, and extensive I/O capabilities such as EIDE, USB 2.0, SDIO, UART, SPI, LPC and SMBus in a single chip. It supports the VIA Chrome® 9 HCM DX9 3D engine, High Definition audio controller, and plenty of display interfaces in its LVDS transmitter, CMOS LCD interface and CRT interface for more flexible multimedia playback options. It also supports dual independent displays on the same platform.
