Technical Specifications
Technical Summary
The Compal LA-3031P revision 1.0 motherboard is designed for the Mobile Yonah and Merom uFCPGA-478 CPU platform with Intel Calistoga GMCH 945GM and ICH7-M core logic. The system BIOS is stored on an SST49LF008A Flash ROM, while the EC firmware is managed by a 25LF080A SPI ROM paired with the SMSC KBC 1021 keyboard controller. Memory architecture consists of two DDR2 SO-DIMM slots supporting DDR2-400/533/667. The integrated audio solution uses the AD1981 codec, and networking is provided by the BCM5753M Gigabit LAN controller. Thermal monitoring is handled by the ADM1032AR sensor, and the CardBus interface is managed by the TI PCI6612 controller. The DVI output is driven by the CH7307C-DE controller.
