Technical Summary

The Compal L360ACN EVT motherboard is built around the AMD Cezanne-H FP6 BGA 1140 processor with DDR4 3200MHz SO-DIMM memory architecture supporting two slots. Graphics options include Nvidia N18P-G61-A (GTX1650), GN20-P0 (RTX3050), or GN20-P1 (RTX3050Ti). The system uses an ENE KB9542B EC/KBC with an IT8176 MCU for keyboard control. BIOS storage is provided by a W25Q16FWZPIQ 2MB SPI ROM. Audio is handled by a Realtek ALC3287 codec, networking by a Realtek RTL8111H LAN IC and Killer 1650i WLAN/BT5.0 module. Charging and power management are managed by a BQ24780S IC. Display connectivity includes an HDMI 2.0 interface via PS8409A re-timing level shifter, and USB-C with PS8719B redrivers. The board also features an RTS5448 card reader controller and PI3EQX12904 PCIe redrivers.
