Lenovo ThinkPad T14 Gen 3 - T16 Gen1 NM-F431 Schematic
Technical Specifications
Technical Summary
This LCFC NM-F431 REV:0.3 motherboard is designed for Lenovo ThinkPad T14/P14s Gen3 and T16/P16s Gen1 platforms, using Project Codes KT4D4, KT4DE, KT6DF, and KT6DG. The platform is built around an Intel Raptor Lake P 6C+8C processor in a BGA1744 package, paired with LPDDR5 4800MHz memory configured across Channel A and Channel B. Discrete graphics is provided by an NVIDIA GN18-S5/QN20-M2 GPU with 4GB GDDR6 on a 64-bit bus. The system uses an MEC1724 embedded controller with a W25Q512JVEIN 64MB SPI flash for EC firmware, and a W25Q128JVSIN 16MB SPI flash for BIOS storage. Audio is handled by an ALC3287-CG codec in a MQFN48 package. Connectivity includes an Intel Jacksonville I219 GbE PHY, Garfield Peak-2 WLAN module, and Parade-PS8409A HDMI retimer. Thunderbolt 4 is supported via Burnside Bridge retimers with a dedicated W25Q80DVUXIE TBT ROM. The charging and PD controller is a TI TPS65994-AE. Additional onboard components include a ST33HTPH2X32AHD4 TPM 2.0 module, LIS2DH12 G-sensor, and a Lenovo Think Engine-3 ASIC.
