Lenovo Ideapad Gaming 3 NM-D191 Schematic
Technical Specifications
Technical Summary
This LCFC L350 A+N1.0 motherboard is built on the AMD RENOIR H platform with DDR4 memory architecture supporting dual-channel SO-DIMM x2 configuration at 3200MT/s. The discrete graphics subsystem features an NV N18P-G61/G62 GPU with 4GB GDDR6 memory across four chips. The system BIOS is stored on a W25Q128JWSIQ SPI ROM with 16MB capacity. Embedded controller functionality is handled by an IT8227E-128/CX in LQFP package. Audio processing is managed by a Realtek ALC3287 HD audio codec. Wired networking is provided by a Realtek RTL8111GU LAN chip, while wireless connectivity uses an NGFF WLAN&BT module. The USB-C charging and power delivery is controlled by a Realtek RTS5449E controller. A PI3EQX7502MZDEX USB 3.0 redriver is used for signal conditioning. The board also includes an NPCT750LABYX TPM module and a Realtek RTS5449E Type-C controller.
