Technical Summary

This Compal LA-3491P revision 0.5 schematic, dated 2007-03-20, documents a motherboard designed around the Mobile Yonah/Merom uFCPGA-478 CPU platform with Intel Calistoga_GM+ ICH7-M core logic. The graphics architecture is based on Intel 945GM or 940GML MCH. System memory consists of two DDR2 SO-DIMM slots supporting dual-channel DDR2-400/533/667. The embedded controller is an SMSC KBC 1070. The BIOS SPI flash is a 25LF080A SPI ROM. Audio is handled by a Conexant CX20549-12 codec with a TPA6017A2 amplifier. Networking is provided by an Intel 82562V 10/100 LAN controller. Thermal monitoring uses an ADM1032AR sensor. The platform also includes a CardBus controller (CB-1410) and a clock generator (ICS9LP306BGLF).
