Technical Specifications
Technical Summary
The Wistron LLW-1/LGG-1 motherboard, project code LLW-1/LGG-1, board number 10282, revision A3, dated November 9, 2010, is built around the Intel Sandy Bridge CPU platform paired with the Cougar Point PCH. Graphics options include UMA-only, discrete Whistler-LP 1G/2G, or Seymour-XT 1G configurations, with VRAM sourced from Samsung or Hynix in 1G or 2G capacities. The embedded controller is a Nuvoton NPCE795, and the audio codec is a CX20671. System memory consists of two unbuffered DDR3 SODIMM slots supporting DDR3 1333MHz. Power management is handled by a BQ24745 battery charger/selector, with multiple DC/DC converters including TPS51218, RT8208B, BD95280, NCP6131, RT9026, and RT9025. The board features an SPI flash for BIOS, a Realtek RTL8111E LAN IC, an EMC2103 thermal sensor, and a media card reader.
