Technical Specifications
Technical Summary
The Wistron Petra Uma-1 motherboard, project code 91.4VM01.001 and board number 48.4VM02.001, is designed for the Intel Ivy Bridge CPU platform with an Intel PCH. It features an NPCE885P EC/KBC and an ALC271X audio codec. The system BIOS is stored on an 8MB SPI Flash ROM. Power management is handled by a BQ24727 charging IC and multiple DC/DC converters including ISL95836HRTZ, RT8207LGQW, RT9025-25ZSP, G978, and TPS51218DSCR. Memory configuration supports two slots of DDRIII RAM operating at 1600/1333 MHz. Networking is provided by an RTL8411 LAN and card reader controller, with 802.11a/b/g wireless support. Thermal monitoring is managed by an NCT7718W sensor.
