Overview
SX8648 Ultra Low Power, Capacitive Button and Slider Touch Controller (8 sensors) with Enhanced LED Drivers ADVANCED COMMUNICATIONS & SENSING DATASHEET GENERAL DESCRIPTION The SX8648 is an ultra low power, fully integrated 8channel solution for capacitive touch-buttons and slider applications.
Unlike many capacitive touch solutions, the SX8648 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 SX8648 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 SX8648 incorporates a versatile firmware t...
