Datasheet Summary
Ultra Low Power, Capacitive Button and Wheel Touch Controller (12 sensors) with Enhanced LED Drivers
ADVANCED MUNICATIONS & SENSING
GENERAL DESCRIPTION
The SX8645 is an ultra low power, fully integrated 12-channel solution for capacitive touch-buttons and wheel applications. Unlike many capacitive touch solutions, the SX8645 Features dedicated capacitive sense inputs (that requires no external ponents) 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 SX8645 includes a capacitive 10 bit ADC analog interface with automatic...
