Technical Specifications
Technical Summary
The Wistron Petra Uma-1 motherboard (Project Code 91.4VM01.001, Board Number 11324, Revision -1) is an Intel Ivy Bridge UMA platform paired with an Intel Panther Point PCH (HM70/77). The system memory architecture consists of two DDRIII SO-DIMM slots supporting DDRIII 1600/1333 and DDRIII 1333/1600. The embedded controller is an NPCE885P28, and the audio codec is an ALC271X. The SPI flash ROM is an 8MB device. Power management is handled by a BQ24727 charger IC with DCBATOUT input architecture, alongside multiple system DC/DC converters including ISL95836HRTZ, TPS51218DSCR, RT8207LGQW, RT9025-25ZSP, and G978. The LAN, card reader, and USB hub functions are integrated into an RTL8411 controller. Thermal monitoring is provided by an NCT7718W sensor. The PCB number is 48.4VM02.011.
