Technical Specifications
Technical Summary
The Wistron Pomona/Texcoco motherboard, project codes 91.4T701.001 and 91.4H201.001, is an AMD K8 Rev. G platform with a Socket A CPU interface. It utilizes an ATI RS690M UMA graphics architecture paired with an SB600 southbridge. The system firmware is stored on a Winbond W25X80-V SPI flash IC. Embedded controller functions are handled by a Winbond WPC8768 KBC. Memory support includes two DDR2 SODIMM slots operating at 533/667/800 MHz. Power management is managed by a combination of ISL6264, TPS51124, ISL6236, TPS51100, and APL5915 regulators, with battery charging controlled by an ISL6255. Networking is provided by a Marvell 88E8071 LAN controller, and audio is handled by a Realtek ALC268 codec. The board also integrates a G792 wireless module, a G1410 card reader, and a CP2211 USB hub controller.
