Technical Summary
This LCFC motherboard schematic, revision 0.1 dated November 10, 2020, documents the HS460, HS560, and HS760 project series with board numbers NM-D471, NM-D472, and NM-D473. The platform is built around an Intel Tiger Lake UP3 15W processor with DDR4 memory configured as Memory Down on Channel A and a Slot-DIMM on Channel B. The system EC is an IT8227VG-128-CX in a VFBGA128 package. The main BIOS SPI ROM is a W25Q128JVSIQ in an SO8 package with 16MB capacity, while a separate W25R64JVSSIQ SO8 8MB ROM is used for EC mirror code. Discrete graphics options include the N18S (U_GPU_GB2E_64) or N17S (U_GPU_GB2D_64) in FCBGA595 packages with 2GB GDDR5 VRAM. The audio codec is a Realtek ALC3287, the thermal sensor is an F75303M, and the card reader controller is an RTS5448.
