Technical Specifications
Technical Summary
The Wistron LC56-14A (Project Code 4PD0MD010001, Revision A3, dated December 02, 2020) is an AMD Renoir APU-based motherboard featuring memory-down DDR4 architecture with four DDR4 MD components per channel (Channel A and Channel B). The system is powered by a BQ25700ARSNR battery charger/selector and multiple DC/DC converters including RT3663BMGQW, RT8231CGQW, APL5934KAI-TR, RT5797ALGQW, RT8231AGQW, TPS51395PRJER, and TPS51393PRJER. The embedded controller is a Nuvoton NPCE386, and the audio codec is a Realtek ALC3287. The BIOS is stored on a 16MB Quad Read SPI flash ROM. Connectivity is managed by a Realtek RTS5457 USB controller and a Realtek card reader controller, with HDMI redriving handled by PS8319B redrivers. The board supports NGFF WLAN and includes a 25W BGA-1140 pin AMD APU.
