Technical Specifications
Technical Summary
This Wistron EA40_HW ULT1 motherboard, documented under project code 91.4YN01.001 and PCB P/N 12243, is built around an Intel Haswell CPU in a BGA1168 package, specifically the BHASWELL-6-GP71.HASWE.G0U model. The platform supports dual-channel DDR3L 1333/1600 memory across two slots. Discrete graphics is provided by an N14P GPU with 2GB of DDR3 VRAM. The system EC/KBC is an ITE8587, and the audio codec is an ALC3225. BIOS storage is handled by an 18MB SPI flash. The charging architecture is managed by a BQ24737 charger IC, with system power delivery handled by a combination of TPS51225, TPS51622, RT8207, SYW232, TPS51728RHA, and RT8208 regulators. Networking and card reading are integrated via a Realtek RTL8411AA-CG controller, while thermal monitoring is provided by an NCT7718W sensor. USB charging is supported by a TPS2546 hub IC.
