Acer A515-56 FH4AT LA-K091P Schematic
Technical Specifications
Technical Summary
This Compal LA-K091P schematic documents the FH5AT/FH4AT motherboard, built around the Intel Tiger Lake UP3 platform with a 1499-pin BGA processor. The board utilizes a dual-channel DDR4 memory architecture, supporting either a single 260-pin DDR4 SO-DIMM module or onboard DDR4 memory configured as 8GB 1024Mbx16 interleaved or 4GB 512Mbx16. System management is handled by an ENEKB9052 EC/KBC, while the BIOS is stored on a 128Mb SPI ROM. Audio is provided by an ALC255 HDA codec. For connectivity, the board integrates a Realtek 8111H Gigabit LAN controller, an RTS5441 Type-C MUX, and a PS8409DDIA HDMI repeater. Power management and charging are managed by an SLGC55544 charger IC.
