Technical Specifications
Technical Summary
This Compal LA5894P motherboard, documented under document number 4019COA revision 1.0 dated 2010-12-29, is designed for the PEW71/91/51 platform. It is built around the Intel Arrandale processor with DDRIII memory and the Ibex Peak-M PCH, utilizing an rPGA988A socket. The graphics subsystem features NV N11P-GV2H, N11P-GE, N12P-GS, and N12P-GV-OP configurations with Optimus technology. System management is handled by an ENE KB926 EC/KBC, while the audio codec is an ALC272X for UMA configurations. The board utilizes a single SPI ROM for BIOS storage. Power management includes a TI TPS6017 charging IC. Memory architecture consists of two 204-pin DDRIII SO-DIMM slots across four banks. Peripheral connectivity is supported by a BCM57780 Gigabit LAN controller and an RTS5160 card reader IC. Clock generation is provided by either an IDT 9LVS3199AKLFT or Realtek RTM890N-631-VB-GRT.
