2.2.4 SOM-4472

Advantech's new SOM-4472 is a new SOM-ETX form factor with an onboard new
VIA Embedded C3 LP 1000 or Eden 667/400 MHz processor. The VIA Eden
processor uses advanced 0.13µ CMOS technology with 128KB L1 cache memory
and 64KB L2 cache memory on die. This board can operate without a fan at
temperatures up to 60° C (140° F) and typically consumes fewer than 14 Watts while
supporting numerous peripherals. This SOM-ETX includes a 4X AGP controller, a
PCI audio interface, a PCI Ethernet interface, and 2 channel LVDS interface. Other
on-board features include an LPT, 4 USBs, IrDA and 2 serial ports: 2 RS-232s.
