Technical Specifications
Technical Summary
This LCFC NM_B321 Rev 0.2 motherboard is built on the AMD FT4 Stoney SOC platform with integrated FCH in a BGA-769 package. The platform supports a single DDR4 SO-DIMM slot for up to 8GB of memory operating at 2133 MT/s or 1866 MT/s. Discrete graphics is provided by an AMD R17M-M1-70 GPU in an S3 package with 4GB or 2GB GDDR5 VRAM configured as 512M*16 or 256M*16 across four chips. The embedded controller is an ITE IT8586E in an LQFP package. System firmware is stored on a SPI ROM. The audio codec and card reader functions are handled by a Realtek RTS5119. Networking includes a Realtek RTL8111G LAN controller and a WLAN&BT module. Thermal monitoring is managed by an NCT7718W sensor. The board also integrates a Parade PS8713 Type-C controller and a Realtek RTS5449 USB3.0 redriver.
