The first chipset to support the VIA C7® processor family, the VIA CN700 is fully optimized to provide an

nnnn

outstanding HD digital media experience. Featuring the high bandwidth V4 bus as well as support for DDR2

nnnn

memory modules, the VIA CN700 delivers a highly advanced solution for developers interested in designing a

nnnn

wide range of powerful embedded and desktop devices.

nnnn

Featuring the VIA UniChrome™ Pro IGP, the chipset provides exceptional graphics performance with its the

nnnn

Chromotion CE Video Display engine and hardware MPEG-2 acceleration. Together with an advanced 2D/3D

nnnn

graphics core, the VIA CN700 offers exceptional playback and streaming of various digital video formats while

nnnn

maintaining ultra low power consumption and exerting minimal load on the processor. The VIACN700 also

nnnn

provides extensive display support with outputs to CRT, LCD and standard definition TV as well as support for

nnnn

HDTV up to 1080i resolution.

nnnn

The CN700 features a robust shared memory architecture and support for up to 2 GB of high bandwidth DDR2

nnnn

533 or DDR400 memory, as well as a high speed V-Link interface for a 533 MB/sec connection to VIA's feature

nnnn

leading South Bridge options.
