Lenovo ThinkBook 13s-IWL BM5884A Schematic
Technical Specifications
Technical Summary
This Bitland V540 motherboard revision 1.32, dated February 20, 2019, is built around the Intel Whiskey Lake U (WHL-U_U42) platform in a BGA1528 package with a TDP of 15W. The system memory architecture consists of two SODIMM slots supporting DDR4. Graphics processing is handled by a discrete AMD R19-m18-70 GPU. The embedded controller is an ITE IT5576E, while the audio codec is an ALC3287. The primary BIOS SPI flash is a Winbond W25Q128JVZPIQ with 128MB capacity. Power management and charging are managed by a TI BQ24780 charger IC and an OZ8690 charger architecture. The board includes a TPM module based on the Z32H320TC, a USB hub controller TPS2546, a card reader controller RTS5457/PS8812, an APX8132 HDMI level shifter, and an RTERDPDDI LAN IC.
