Technical Specifications
Technical Summary
The Wistron JV50-CP motherboard, project code 91.4GD01.001 and PCB number 48.4GD01.0SB revision SB 09285, is designed for Intel Arrandale or Clarksfield CPU platforms paired with an Intel PCH. Graphics are handled by an ATI Madison or Park PCI Express Graphics solution. The system uses an NPCE781B EC/KBC with a dedicated 128KB Flash ROM, and the main BIOS is stored on a 4MB Flash ROM. Audio is managed by an ALC272 codec, and networking is provided by a BCM57780 Giga LAN controller. Power management includes an ISL88731A charger IC and multiple DC/DC converters such as TPS51117, TPS51123, ISL62881, and ISL62882. Memory configuration supports DDRIII 800/1066/1333 across two slots in Channel A and Channel B. Additional features include an AU6433 card reader, G78739 thermal sensor, and support for WLAN, Bluetooth, and a digital display interface.
