Lenovo S540 Compal LA-H091P Schematic
Technical Specifications
Technical Summary
This Compal LA-H091P revision 1.0 motherboard schematic, dated 2018-12-20, details an AMD Picasso FP5 APU platform with DDR4 memory architecture. The system utilizes an 8MB SPI ROM for BIOS storage and is managed by an ENE KB9022 embedded controller. Audio processing is handled by a Synaptics CX11880 codec, while a Realtek RTS5232 provides SD card reader functionality. USB connectivity is supported by Parade PS8713B USB redrivers and a Realtek RTS5448 Type-C controller with CC/EC logic. The HDMI interface is driven by a Parade PS8407A level shifter. A TI SN1702001RTER IC manages USB charging functions. The design supports both on-board DDR4 SO-DIMM and soldered memory configurations, along with NGFF PCIe SSD and WLAN/BT connectivity.
