WIRELESS & SENSING SX8644 Ultra Low Power, Capacitive Button and Slider Touch Controller (12 sensors) with Enhanced LED Drivers DATASHEET GENERAL DESCRIPTION The SX8644 is an ultra low power, fully integrated 12-channel solution for capacitive touch-buttons and slider applications.
Unlike many capacitive touch solutions, the SX8644 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.
The SX8644 includes a capacitive 10 bit ADC analog interface with automatic compensation up to ...
