Technical Specifications
Technical Summary
This Wistron Calado-1 motherboard, project code 91.4X401.001 with board number 07227 revision -1, is built around the Intel GM965 or GL960 chipset paired with an ICH8M southbridge. The platform supports a Merom or Celeron M mobile CPU in a 479-pin package. System memory is DDR2 running at 533 or 667 MHz. The embedded controller is a Winbond WPC8763L, and the BIOS SPI flash is a W25X80-V in an SSBIOS package. Audio is handled by a Realtek ALC268 codec. The charging subsystem uses a MAX8731 charger controller with a MAX8770 for battery management. Power regulation is managed by multiple ICs including TPS51120, TPS51124, TPS51100, APL5915, and APL5913. Integrated graphics are provided by the GM965 (GMA X3100) or GL960 (GMA 3000). Networking is via a Broadcom BCM5787MKMLG gigabit LAN controller, and a Realtek RTS5158 5-in-1 card reader is included.
