SX8645 - Capacitive Button and Wheel Touch Controller

Description

The SX8645 is an ultra low power, fully integrated 12-channel solution for capacitive touch-buttons and wheel applications.

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.

SX8645 Ultra Low Power, Capacitive Button and Wheel Touch Controller (12 sensors) with Enhanced LED Drivers ADVANCED COMMUNICATIONS & SENSING DATASHEET 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 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.
