Technical Specifications
Technical Summary
This Compal LS-4901P Cap sensor board schematic, revision 0.5, dated May 20, 2009, is a proprietary Compal Electronics document. The board is a sub-board, not a main motherboard, and is designed around a Cypress CY8C20446 PSoC (Programmable System-on-Chip) microcontroller in a SOT-23 package, serving as the EC/KBC for controlling capacitive touch buttons and LED indicators. The board includes interfaces for buttons such as Mute, Quick Look, Quick Web, Wireless, Touch Pad, and Volume Up/Down, along with various LED indicators for status. The design incorporates a hot bar FFC connector and an FFC connector for board interconnection.
