Lenovo S145-15AST NM-C171 Schematic
Technical Specifications
Technical Summary
The LCFC S145AST motherboard, revision 0.2, dated 2018-10, is built around the AMD FT4 Stoney SOC platform with integrated FCH in a BGA-769 package. Graphics are handled by a discrete AMD R17M-M1-70 GPU with 2GB GDDR5 VRAM configured as 256x32 4x Gen3. System memory is provided by a single DDR4 SO-DIMM slot operating in single-channel mode. The embedded controller is an ITE IT8586E-LQFP. Audio codec and card reader functions are integrated into a Realtek RTS5119. The system BIOS is stored on a SPI ROM. Thermal monitoring is managed by a F75303M sensor.
