Lenovo AIO 520-24ICB LA-F901P Rev 1.0 Schematic
Technical Specifications
Technical Summary
The Compal LA-F901P M/B revision 0.1 is an Intel Coffee Lake-S platform motherboard with DDR4 memory support and an AMD GPU (M17) graphics architecture. The board is built around the Intel B360 PCH and features an LGA1151 CPU socket. The system EC is an NCT6685D3W, with its firmware stored on a W25X20CLSNIG (128KB) SPI flash. The main BIOS is a W25Q64FVSSIQ 16MB SPI ROM. Audio is handled by a Realtek ALC274 codec, while networking is provided by a Realtek RTL8111G LAN IC. The board supports DDR4-SO-DIMM memory across two banks (Channel A and Channel B). A Realtek RTS5170 card reader is integrated, and HDMI conversion is managed by an RTD2136N converter or RTD2506S-CG scalar.
