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

Key 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 SX8645 includes a capacitive 10 bit ADC analog interface with automatic compensation up to 100pF. The high resolution capacitive sensing supports a wide variety of touch pad sizes and shapes and allows capacitive buttons to be created u.
