acer s7-391 wistron storm rev -1
Technical Specifications
Technical Summary
This Wistron Storm-1 motherboard, documented under project code 91.4WE01.001 and PCB P/N 48.4WE05.0SA revision 12223-1, is built around an Intel IVY Bridge CPU platform paired with the Intel HM77 PCH. The graphics architecture is Intel PCH UMA, with no discrete GPU. System memory consists of DDR3L 1333 in a Memory Down configuration. The embedded controller is an ITE IT8518VG, and the audio codec is an ALC271. The main BIOS is stored on a 4MB SPI flash ROM, while a separate 2MB SPI flash ROM is used for the EC. Power management and charging are handled by a BQ24745RHD TI charger IC, with multiple system DC/DC converters including the RT8208BGQW, NCP6131, UP6165BQKF, UP6183PQAG, UP6128PQD, RT9025-25PSP, and RT90253. The board features a RTS5138 card reader and LAN controller, a Cactus-Ridge USB 3.0 hub, and a MAX14521E keyboard backlight driver.
