Lenovo A540-27ICB IB360SL2 Schematic
Technical Specifications
Technical Summary
The Asia Vital Components A540-27ICB V1.1 motherboard is built on the Coffee Lake-S platform with an LGA 1151 socket and B360 PCH. It features an AMD R19M-G40-70 discrete GPU and supports DDR4 memory via two SODIMM slots across two channels. The system utilizes an ITE 8632E/A EC/KBC and a single 16MB SPI flash ROM for BIOS storage. Audio is handled by a CX11970 High Definition Audio codec. Networking includes a Realtek RTL8111H LAN controller and AMP 5825/5720 WiFi modules. The board incorporates a GL835L USB hub and SD card reader, an RTD2785 DP to LVDS bridge for display output, and an INA300 charging IC. The power sequence is managed through a multi-stage G3 to S0 process involving the EC, PCH, and VR controllers.
