Technical Specifications
Technical Summary
This Compal LA-3281 motherboard schematic, revision 0.3, dated 2005/10/06, is designed for the Mobile Yonah CPU platform in uFCPGA-478/uFCBGA-479 packaging. The core logic is built around the Intel Calistoga GMCH (945GM graphics) and the Intel ICH7-M southbridge. System memory consists of two DDR2-SO-DIMM slots supporting dual-channel DDR2-667. The embedded controller is an ENE KB910L, and the audio codec is an ALC 861VDA. The board utilizes a Smart Battery charging architecture. Storage and connectivity are managed by an ENE CB1410 CardBus controller, a RICOH R5C832 card reader, and a Realtek RTL8100CL 10/100M LAN controller. The BIOS is stored across four banks (0, 1, 2, 3). The clock generation is handled by an ICS9LPR325AKLFT and an ICS954226. The PCB number is LA3281P.
