Technical Specifications
Technical Summary
The LCFC S145AST motherboard, revision 0.2 dated 2018-10, is built around the AMD FT4 Stoney SOC with DDR4 platform. The integrated graphics subsystem utilizes an AMD R17M-M1-70 GPU with 2GB GDDR5 VRAM configured as 256*32 across 4x Gen3 lanes. 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 handled by a Realtek RTS5119. The BIOS resides on a SPI ROM. Thermal monitoring is managed by a F75303M sensor. Wireless connectivity is supported via an NGFF card for WLAN and Bluetooth on Key E.
