Technical Summary

This Wistron KABINI reference design, documented under Project Codes 91.4YU01.001 (EG50-KB), 91.4ZK01.001 (EA50-KB), and 91.4ZF01.001 (EA40-KB), is built around the AMD KABINI FT3 APU with integrated DX11 IGP graphics. The motherboard utilizes an 8MB SPI ROM for BIOS storage and features an ITE 8587 EC/KBC. Power management is handled by a multi-IC solution including BQ24737 for charging, ISL6267 and RT8068 for CPU core voltage regulation, and TPS51225, RT82070, RT82074, TPS51728, and SY8208 for system and VGA power rails. Memory is configured as single-channel DDR3L. The platform integrates a QCA8175 combo WLAN and Bluetooth controller, a Realtek ALC3225 audio codec, and a GbE LAN controller. The block diagram confirms support for PCIe Gen2, USB 3.0, SATA, HDMI, eDP, and VGA outputs.
