Overview
WIRELESS & SENSING SX8636 Low Power, Capacitive Button Touch Controller (8 sensors) with Enhanced LED Drivers and Proximity Sensing GENERAL DESCRIPTION The SX8636 is an ultra low power, fully integrated 8channel solution for capacitive touch-buttons and proximity detection applications.
Unlike many capacitive touch solutions, the SX8636 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 SX8636 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 using thick overlay materials (up to 5mm) for an extremely robust and ESD immune system design.
The SX8636 incorporates a versatile firmware that was s...
