Catalog excerpts

CX700M (Single-Chip)-1

Unified Digital Media IGP * CX700M2 has Macrovision® support The VIA CX700M 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 designs, 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 (37.5 mm x 37.5 mm) — representing a saving of over 34% in board real estate. This represents 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. Complementing VIA's Nano™, C7® or Eden™ processor 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.
