Technical Specifications
Technical Summary
The Wistron EA53-BM-1 motherboard, documented under project code 4PD037010001 and PCB number 14222, is built around the Intel Bay Trail-M CPU platform. The system firmware is stored on a W25Q64FW SPI flash IC. Embedded controller functions are handled by an NPCE985PB KBC. Memory configuration consists of a single DDR3L 1333MHz channel A slot. The charging subsystem is managed by an HPA02224 charger IC, with system power regulation provided by RT6575B, TPS51716, RT9198, and APL5930 DC/DC converters and LDOs. Audio is processed by an ALC2832 HD Audio Codec. Networking is supported by a Realtek RTL8111G LAN IC and a WLAN & BT combo module. A GL850G USB 2.0 hub expands USB connectivity, and a Realtek card reader is integrated. The board revision is A3, dated June 4, 2014.
