hp ls-4901p rev-0.5 20090520c 1
Technical Specifications
Technical Summary
This Compal LS-4901P revision 0.5 document, dated May 20, 2009, covers a Cap Sensor Board and Switch Board. The board is built around a Cypress CY8C20446 PSoC microcontroller, which serves as the embedded controller for managing capacitive touch sensing and LED indicators. The design integrates multiple buttons including Mute, Quick Look, QWeb, Wireless, Touch, and Volume Up/Down, alongside a suite of status LEDs for WLAN, Quick Look, Quick Web, Touch Pad, Caps, Num, Mute, and Volume. The PSoC's programmable nature allows for in-system configuration of its GPIO and capacitive sensing blocks. The board uses a 1.0mm pitch FFC connector for its main interface and includes specific component changes documented in the change list, such as the modification from a slider bar to discrete volume buttons and the removal of MOSFETs for WLAN LED control.
