Acer SP714-61N Compal LA-K501P Schematic
Technical Specifications
Technical Summary
The Compal GH4PX (LA-K501P) is a 13.3-inch convertible motherboard powered by the Qualcomm SC8180X octa-core 7nm FinFET SoC. The platform integrates LPDDR4 memory configured as 64-bit dual-channel with two 16GB packages. System power management is handled by a suite of Qualcomm PMICs including PMC8180C, dual PMC8180, PMK8002, and dual PMC1000H. Charging is managed by the SMB2351 2S charger IC. The embedded controller is an ENE KB9022. Audio processing is provided by the WCD9341 codec paired with dual WSA8815 amplifiers. Wireless connectivity uses the WCN3998 module. The board includes dual FSUSB42UMX USB-C multiplexers for USB3.1 Gen2 and DP Alt Mode support.
