Technical Specifications
Technical Summary
The Wistron Homa-1 (TM15") motherboard, documented under A3157 dated April 3, 2008, is built around the Mobile CPU Cantiga/Penryn platform with an ICH9M southbridge. It features integrated graphics and supports DDR2 memory at 667/800 MHz. The system uses a Winbond W25X80 SPI flash for BIOS storage and a Winbond EC/KBC controller. Power management is handled by a BQ24750 charger IC and multiple DC/DC converters including TPS51125, TPS51100, TPS51124, APL5912, ISL6266A, and ISL6263G. Networking is provided by a BCM5764M gigabit LAN controller, while audio is managed by a RealTek ALC268 codec. The board also incorporates an OZ711MZ card reader controller. The PCB is identified as 48.4Z401.011 with revision 07245-1.
