Technical Specifications
Technical Summary
This Wistron Corporation motherboard, documented under number A31101 dated March 7, 2011, is built around the Intel Sandy Bridge CPU platform paired with the Intel Cougar Point PCH. The system utilizes integrated graphics from the GMCH GFX core and supports dual-channel DDR3 1333MHz memory via two 204-pin SODIMM slots. Power management is handled by a TPS51220ARSN system DC/DC converter, a BQ24742 battery charger/selector, and multiple VT and MAXIM regulators. The embedded controller is a VBG25HV KBC communicating over the LPC bus. Audio is provided by an ALC269 codec over the Azalia/HD Audio interface. The board features an SPI flash for BIOS storage, an EMC1428 thermal sensor on the SMBus, a 4-in-1 media card reader, a uPD720200A USB 3.0 hub controller, an RTL8111 Gigabit LAN IC, and an Intel LEWISVILLE WLAN card. An FDILVDS level shifter supports the HDMI port.
