| Via ships "world's smallest mainboard" |
May 22, 2007
 PC chipset and board-maker Via Technologies today announced availability of the "world's smallest mainboard" -- the first shipping board based on its recently unveiled, incredibly small (100 x 72mm) "pico-ITX" motherboard format. The Epia PX10000G is "available now for developers... in limited limited quantities," the company said.
Via offered an early look at its pico-ITX design in January, at an event associated with the Consumer Electronics Show in Las Vegas. Then, in April, the company revealed further details of its VT6047 pico-ITX hardware reference design.

At 3.9 x 2.8 inches (100 x 72mm), Via's pico-ITX motherboard form-factor represents "the smallest complete x86 mainboard in the industry," Via claims. Pico-ITX format boards occupy half the surface area of nano-ITX boards, and a quarter that of boards based on the now 5-year-old mini-ITX standard. This miniaturization has been enabled in part by an 82 percent real estate reduction of Via's chipsets, which have shrunk from 50 x 50mm in mini-ITX's original "Socket 370" processors to just 21 x 21mm for the "nanoBGA" package used for Via's current-generation C7 processors.

The Epia PX10000G board that Via is now shipping is based on a 1GHz Via C7 processor and provides an SO-DIMM socket that accommodates up to 1GB of DDR2 533 SDRAM memory. The 10-layer board also integrates Via's VX700 system media processor, which features Via's UniChrome Pro II IGP 3D/2D graphics core, MPEG-2/-4, and WMV9 hardware decoding acceleration. Via notes that the board's graphics engine can support the high resolutions required for displaying HD DVD playback.
Numerous input/output connections -- mostly accessible by means of pin-header connectors, due to space restrictions -- provide a broad set of standard PC I/O interfaces. These include 10/100 Mbps Ethernet, USB2.0, serial COM port, IDE, SATA, PS2 mouse/keyboard, audio, and video.
The board uses what Via calls a pico-ITX power connector. As far as power consumption is concerned, the board "can run standard productivity and multimedia applications at under 13W," Via says.
