SX8635规格书详情
描述 Description
The SX8635 is an ultra low power, fully integrated 12-channel solution for capacitive touch-buttons andwheel with proximity detection applications. Unlike many capacitive touch solutions, the SX8635 features dedicated capacitive sense inputs (that requires no external components) in addition to 8 general purpose I/O ports (GPIO). Each GPIO is typically configured as LED driver with independent PWM source for enhanced lighting control such as intensity and fading.
