Technical Specifications
Technical Summary
The Compal EDL71 LA-23511B Rev 1B motherboard is designed for the Intel Pentium-M processor in a uFCPGA socket, paired with the Intel Alviso chipset and ICH6-M southbridge. Graphics are handled by an ATI M24 GPU with a dedicated frame buffer. The board supports two DDRI-DIMM slots across four memory banks. Power management is handled by a MAX1902 DC/DC converter for 3V/5V/12V rails, a MAX1532 for CPU core, an ALP5331 for 1.25V, a MAX8743 for 1.5V/VCCP, and a FAN5234 for 2.5V, with charging controlled by a PMB3887 IC. Audio is provided by an ALC250 AC97 codec, networking by an RTL8110SBL/8100CL LAN controller, and card reading by an ENE CB712 controller. Thermal monitoring uses G781 sensors for both CPU and VGA. The EC flash ROM is an SST39VF040 parallel flash device.
