lenovo thinkpad x220 wistron dasher-1 ldb-1 schematic 1
Technical Specifications
Technical Summary
The Wistron Dasher-1 (Project Code Dasher-1, Board Number A31101, Revision A3, dated January 12, 2011) is built on the Intel Sandy Bridge CPU platform with an Intel Cougar Point PCH. Graphics are provided by the integrated Intel Sandy Bridge graphics core. The system uses an SPI-FLASH for BIOS storage and is managed by a Thinker-1 EC/KBC. Memory architecture consists of dual-channel unbuffered DDR3 1333MHz SODIMMs across two slots. Power management includes a BQ24742 battery charger/selector and multiple DC/DC converters such as the TPS51220ARSN, VT1316/VT1317, VT357FCX, VT356FCX, MAX1510, and TPS62060. Connectivity is supported by an ALC audio codec, a USB2514B USB hub, an Intel LEWISVILLE WLAN card, a Rinken-2 LAN IC, and a PI3L500AZFEX HDMI level shifter. Thermal monitoring is handled by an EMC1428 sensor, and a R4F2113 IC manages the media card reader interface.
