Technical Specifications
Technical Summary
This Wistron EA30_BM motherboard, revision A3, is built around the Intel Bay Trail-M CPU platform. The system firmware is stored on an 8MB SPI flash, specifically a W25Q64FWSSIG IC. Embedded controller functions are handled by an NPCE985P. Memory configuration consists of a single DDR3L 1333MHz channel A slot. The integrated GPU core is regulated by an RT8812 controller. Charging is managed by a BQ24727RGRR charger IC. Audio is provided by an ALC2832 codec, while networking and card reader duties are handled by a Realtek RTL8411B. The power delivery subsystem includes TPS51225, ISL95833, SY8208, TLV70218, TLV70012, SYW2325, RT8812, TPS22966, and TPS22965 regulators and load switches. Wireless connectivity is supported via a WLAN and Bluetooth combo module.
