VIA Surfboard C855 Reference Design

Riding the crest of the mobile wave

The new VIA Surfboard C855 Reference Design opens up the rapidly growing mini-notebook market to device manufacturers looking for the latest technological advancements in mobile component design.

With all the critical building blocks, including the VIA C7-M ULV processor, the brand new VIA VX855 MSP chipset, and VIA audio, networking and communications chips, the VIA Surfboard C855 provides the total silicon platform upon which to build exciting, new mini-notebook devices.

The VIA Surfboard C855 meets demand for better visual computing from mini-notebook devices by providing flawless playback of high bit-rate 1080p HD video, which along with support for internal display resolutions of up to 1366 x 768 pixels and external display resolutions up to 1920 x 1440 pixels, and a wide range of connectivity options, allows for a rich on-the-go multimedia experience.

Advanced HD Video Playback

While consumers have been quick to endorse the mini-notebook form factor and the convenience provided by its connectivity and web surfing capabilities, the rise of HD video has resulted in a growing demand for greater graphics processing power.

The new VIA VX855 Media System Processor is a power efficient, highly integrated all-in-one chipset that introduces the advantages of next-generation high-definition video compression algorithms to ultra-mobile devices. The VIA VX855 enables the VIA Surfboard C855 to support hardware acceleration of leading video standards including H.264, MPEG-2, MPEG-4 and VC-1 at the highest bit-rates and resolutions, greatly reducing the workload and thus the power consumption of the processor.

Low Power, Long Battery Life

VIA processing components enjoy a strong market reputation for cool operation and ultra-low power draw. Thanks to the highly efficient heat dissipation of the VIA C7-M processor and the 2.3W TDP of the VIA VX855 chipset, the VIA Surfboard C855 offers system developers a cool, quiet and low power foundation to create innovative designs around.

And with battery life one of the most desirable features in today’s mobile devices, the VIA Surfboard’s ultra-low power consumption and support for power management features such as screen auto-dim, allows for an even longer, fuller mobile computing experience.


VIA's expertise in component design and fully integrated reference platforms assist developers in reducing both time-to-market and R&D expense for new products.

Additionally, members of VIA's Global Mobility Bazaar (GMB) Alliance, which links leading Chinese PC manufacturing and infrastructure partners in order to drive the rapid global adoption of mobile computing devices, will have access to all the component vendor technology and expertise necessary to quickly and affordably bring sophisticated designs based on the VIA Surfboard C855 to mobile users.
