Technical Summary
This Compal LA-K901P revision 0.1 motherboard is built around an AMD FP5 APU with DDR4 memory support, utilizing two DDR4-SO-DIMM banks. The platform integrates an AMD APU (FP5 Type2) with a lidless BGA package featuring a 0.64mm ball pitch, 1140 pins, and dimensions of 25mm x 35mm, rated at 15W with a maximum frequency of 2400 MHz. The system is managed by an Nuvoton NCT6686DL EC/KBC, which is supported by a dedicated W25X20CLSNIG 2Mb EC flash ROM. The main BIOS SPI flash is a W25Q128FWSIQ 16MB IC. Audio processing is handled by a Realtek ALC233 codec, while networking is provided by a Realtek RTL8111G/H LAN controller. A Realtek RTS5140 card reader and a GL852 USB 2.0 hub are also present. The HDMI output is managed by a RTD2136Ne level shifter, and the charging circuit utilizes a TI 3110 IC.
