Lenovo Flex 5 203021-1 Schematic
Technical Specifications
Technical Summary
This Wistron LC56-14A Rev A3 motherboard, dated December 2, 2020, is built around an AMD APU Renoir platform. The system management is handled by a Nuvoton NPCE386 EC/KBC, while audio processing is managed by a Realtek ALC3287 codec. The board utilizes a 16MB Quad Read SPI flash ROM for BIOS storage. Power management includes a BQ25700ARSNR battery charger/selector and multiple DC/DC converters such as the RT3663BMGQW, RT8231CGQW, and TPS51395PRJER. Memory architecture consists of DDR4 3200MHz memory down configurations supporting both SDP and DDP. Connectivity is provided by a Realtek RTS5457 USB hub/LAN controller, a Realtek card reader, and an NGFF WLAN module. Display output is supported via a PS8319B re-driver for HDMI.
