ibm x220t dasher-1h0227 schematic 1
Technical Specifications
Technical Summary
The Wistron Dasher-1 (A31101 Rev A3) motherboard is built around the Intel Sandy Bridge CPU platform paired with the Intel Cougar Point PCH. Graphics are handled by the integrated Sandy Bridge GPU core. System memory consists of two unbuffered DDR3 1333MHz SODIMM slots. The embedded controller is a Thinker-1 device. The BIOS is stored on a SPI-FLASH IC. Power management is handled by a TPS51220ARSN system DC/DC converter, a BQ24742 battery charger/selector, and multiple VT1316/VT1317, VT357FCX, VT356FCX, VT355FCX, and TPS62060 voltage regulators. The audio codec is an ALC device. Networking includes an Intel LEWISVILLE WLAN card and a Rinken-2 LAN IC. A USB2514B USB hub and an EMC1428 thermal sensor are also present. The board features a MAX1510 HDMI level shifter and an R4F2113 card reader controller.
