CX700M Chipset

The VIA CX700M system media processor, an all-in-one digital media IGP chipset, integrates premium graphics, audio, memory, storage, and HDTV support all in a single chip design. This unified design enables the creation of smaller form factor systems, reduced power consumption, and easier cooling, all of which opens the door for an expanded range of embedded solutions. This is all done in a single chip package exactly the same size as a North bridge, i.e. 37.5mm x 37.5mm, representing a saving of over 34% in board real estate, representing a major breakthrough for the embedded industry where ultra compactness is essential, and will have significant benefit for embedded boards such as PC/104 and VIA EPIA mainboards. In addition, VIA offers the VIA CX700M2 supporting Macrovision copy protection. Complementing the power-efficient VIA C7^® and fanless VIA Eden processors it supports, the VIA CX700M is based on a highly sophisticated power efficient architecture that enables such rich integration into a compact package with a maximum power envelope of just 3.5 watts. A number of key power management technologies are incorporated that monitor activity and dynamically control power according to system load requirements. Targeted for key embedded applications such as Point of Sales (POS) equipment, industrial PCs (IPC) and ultra compact, low power desktop systems such as thin clients, the VIA CX700M has been designed from the ground up to deliver excellent performance, features and power efficiency. The reduction in board space and operating power requirements together with the extensive multimedia, memory, connectivity and display flexibility provides embedded customers with the ideal chipset to take their ultra compact systems to the next stage. The VIA CX700M features the VIA C-Pro II Integrated Graphics Processor (IGP) ensuring optimal performance for all multimedia, entertainment, and productivity applications. With an internal data flow equivalent to the latest AGP 8X graphics cards, a 200MHz 2D/3D graphics engine and features dedicated 128-bit data paths for pixel data flow and texture/command access. The VIA C-Pro IGP graphics core also features the C-Motion video engine raising the bar for digital entertainment support on PC systems. The C-Motion video engine employs a multi-faceted approach to displaying multimedia content, implementing a number of advanced tools at every stage of video processing. These include integrated MPEG-2, MPEG-4, and WMV9 decoding, for flawless digital video playback with ultra-low CPU-utilization, and advanced rendering tools such as Adaptive De-Interlacing and Video Deblocking, which ensure clearer playback of digital content on all display devices.

Benefits of VIA CX700M

Advanced HDTV Display Support

Flexibility is extended to display technologies, with the VIA CX700M integrating a built in HDTV encoder for connection to the latest displays, and multi-configuration LVDS/DVI transmitter.

VIA C-Pro Graphics Core

With an internal data flow equivalent to what is available to the latest AGP 8X graphics cards, VIA C-Pro II has a separate 128-bit data path between the North Bridge for pixel data flow and texture/command access. Separate 128-bit 2D and 3D graphics engines ensure optimal performance for all multimedia, entertainment, and productivity applications.

Flawless Digital Media Playback

VIA C-Pro II includes native support for the most popular digital video and audio formats through hardware MPEG-2/MPEG-4/WMV9playback and acclaimed VIA Vinyl HD Audio suite, supporting up to eight high definition channels delivering a richer all-around digital media experience.

Advanced Memory Controller

VIA’s renowned memory controller technology has been incorporated into the VIA CX700M, with support for both DDR400 and the high-bandwidth DDR2 533 memory up to 2GB with ECC capability, and 32-bit as well as 64-bit system memory to extend performance, design and cost flexibility to developers.

VIA Advanced Connectivity

The VIA CX700M offers broad connectivity with support for SATA, SATA II and PATA drives, two COM and six USB2.0 ports, and four PCI slots, allowing for considerable flexibility in board configuration. Additionally, developers can also integrate support for ISA through an ITE PCI bridge chip, combining legacy ISA connectivity with high bandwidth DDR2 memory support for more powerful embedded systems.

Unified VIA Hyperion Pro Drivers

VIA’s unified approach to drivers has been established for eight generations of chipsets, allowing end users to benefit from seamless hardware and software compatibility.
