Lenovo 15ITL 202 - LCFC NM-D211 Schematic
Technical Specifications
Technical Summary
This LCFC S550-IT (LC161) motherboard is built on the Tiger Lake_U42 platform with DDR4 memory down architecture. The system BIOS is stored on a W25Q128JVSIQ_SO8 16MB SPI flash, while the EC firmware resides on a separate W25Q80JV SPI ROM. The embedded controller is an ITE IT8827, and audio is handled by a Realtek ALC3287 codec. Thermal management is provided by an NCT7719W sensor, and an NCT7718W manages the SD card reader. The charging solution uses a TPS65994 PD controller, and the integrated LAN is provided by an Intel MCP. Wireless connectivity is supported via a CNVi interface.
