Technical Specifications
Technical Summary
The Wistron Storm-1 motherboard, project code 91.4WE01.001 with board number 48.4WE05.0SA revision 12223-1, is an Intel IVY Bridge UMA platform paired with an Intel HM77 PCH. The system utilizes a 4MB SPI Flash ROM for BIOS storage and is managed by an ITE IT8518VG EC/KBC. Memory architecture consists of two DDR3L 1333 Memory Down modules. Power management is handled by a TI BQ24745RHD charger and a comprehensive array of DC/DC converters including RT8208BGQW, NCP6131S52MNR, UP6165BQKF, UP6183PQAG, UP6128PQDD, RT90253, NCP5911MNTBG, APL5916KAI, and RT9025-25PSP. Audio is provided by an ALC271 codec, and connectivity includes an RTS5138 card reader, LGA WLAN+BT module, and ITE IT8518VG LAN controller. Thermal monitoring is performed by an NCT 7718 sensor, and keyboard backlighting is driven by a MAX14521E IC.
