Technical Summary

The Compal LA-3491P revision 0.5 motherboard, dated 2007-03-20, is built around the Mobile Yonah/Merom uFCPGA-478 CPU platform with Intel Calistoga MCH (945GM or 940GML) and ICH7-M southbridge core logic. System management is handled by an SMSC KBC 1070 EC/KBC controller. The BIOS is stored on a 25LF080A SPI ROM. Memory configuration consists of two DDR2 SO-DIMM slots supporting DDR2-400/533/667. Audio is provided by a Conexant CX20549-12 codec with a TPA6017A2 amplifier. Networking includes an Intel 82562V 10/100 LAN controller and a Mini-Card WLAN slot. A CB-1410 CardBus controller provides expansion, and thermal monitoring is managed by an ADM1032AR sensor. The charging architecture is based on the Volga 2.0 power circuit.
