Technical Specifications
Technical Summary
The Wistron Fonseca 14.1" DIS motherboard, project code 91.4GQ01.001 with board number 91.4GQ01.0SB revision X01, is built around the Intel Ibex Peak-M platform supporting an rPGA988A socket for Mobile Arrandale CPUs. Graphics are handled by an ATI M92-LP discrete GPU with dedicated DDR3 VRAM. The embedded controller is an ECE 1077, and system audio is provided by an IDT92HD81 Azalia CODEC. The BIOS is stored on a 64Mb SPI flash. Power management is handled by a TI BQ24745 battery charger, with system DC/DC conversion managed by ISL62883, TPS51116, TPS51511, TPS51125, and TPS51218 regulators, alongside RT9035 LDOs. Memory architecture supports two DDR3 DIMM slots across Channel A and Channel B. The board integrates a BCM5761E LAN controller, an R5U242 card reader, and a MAX4885EETG HDMI level shifter.
