VIA introduces 'world's smallest' x86 form factor
A new, even smaller form factor has joined VIA's ITX portfolio. With the now five-year-old Mini-ITX standard, which specifies 17cm x 17cm (6.7" x 6.7") motherboards, and the three-year-old Nano-ITX standard, which is 50% smaller at 12cm x 12cm (4.7" x 4.7",) comes VIA's latest effort: Pico-ITX. This new form factor specifies motherboards measuring only 10cm x 7.2cm, or 3.9" x 2.8"—tiny enough to fit in somebody's palm. VIA has already released a Pico-ITX reference motherboard, the VT6047, and it intends to announce the first commercial products based on the new form factor "shortly." As luck would have it, VIA Arena has also posted a preview of the Pico-ITX form factor that includes several pictures of the VT6047 reference mobo.
According to VIA, the VT6047 Pico-ITX board is designed to accommodate a low-power VIA C7 or fan-less VIA Eden processor enclosed in a 21mm x 21mm nanoBGA2 package. The top of the board houses the processor, chipset, Ethernet controller, BIOS chip, and connectors for power, IDE, Serial ATA, USB, audio, video, and other miscellaneous I/O. The bottom of the board sports a 200-pin DDR2 SO-DIMM slot, a battery, and an HD audio codec chip. More details about the design are available in VIA's Pico-ITX form factor white paper, which can be viewed here (in PDF format.)
