Technical Specifications
Technical Summary
The Wistron JV50-CP motherboard, project code 91.4GD01.001, revision SB, dated August 27, 2009, is built around the Intel Arrandale or Clarksfield CPU platform with an Intel PCH. Graphics are handled by an ATI Madison or Park GPU via PCI Express Graphics. The system uses an NPCE781B EC/KBC and an ALC272 audio codec. BIOS is stored on a 4MB Flash ROM. Power management includes an ISL88731A charger and multiple DC/DC converters such as the TPS51117, RT9025, ISL62881, ISL62882, and TPS51123. Memory configuration supports DDRIII 800/1066/1333 across two slots in Channel A and Channel B. Connectivity features include a BCM57780 Gigabit LAN controller, an AU6433 card reader, and WLAN via Mini-Card. Thermal monitoring is provided by a G78739 sensor.
