Technical Specifications
Technical Summary
The Wistron Storm-SD motherboard, project code 91.4WE01.001 and board number 48.4WE01.0SA revision 11325-SD, is an Intel Chief River platform designed for Ivy Bridge BGA 1023 Pin ULV processors paired with a PCH HM77 chipset. The system uses UMA graphics architecture with DDRIII 1066/1333 memory configured as two Memory Down channels. The embedded controller is an ITE IT8518VG, and the audio codec is an ALC271. The BIOS is stored on a 2MB SPI Flash ROM. Power management is handled by a TI BQ24745RHD charger IC and multiple DC/DC converters including RT8208BGQW, NCP6131S52MN, UP6165BQKF, UP6183PQAG, UP6128PQDD, RT90253, NCP5911MNTBG, APL5916KAI, and RT9025-25PSP. The board includes an NCT7718 thermal sensor, an RTS5138 card reader IC, and LGA WLAN+BT wireless connectivity.
