Technical Specifications
Technical Summary
This Compal LA-K671P revision 1.0 motherboard schematic, dated 2020-10-06, details an Intel Ice Lake-U processor platform with DDR4 memory support. The system utilizes two DDR4 SO-DIMM slots for memory expansion. The embedded controller is an ENE KB9052, and the audio subsystem is handled by a Realtek ALC3287 codec. A 16 MB SPI ROM is designated for BIOS/SPI flash storage. Wired networking is provided by a Realtek RTL8111H LAN IC, while wireless connectivity is supported via an Intel CNVi interface. The charging and USB-C controller is a Realtek RTS5448. Additional integrated controllers include a Realtek RTS5146 card reader, a Genesys GL835-OGYL34 USB hub controller, and TPM support via either a Nuvoton NPCT750LADYX or ST ST33HTPH2X32AHD8.
