Additional preview pages of the SX8663 datasheet.

The SX8663 is an ultra low power, fully integrated 12-channel solution for capacitive touch-button matrix (up to 36 keys) and proximity applications.

dedicated capacitive sense inputs (that requires no external components) in addition to 8 general purpose I/O ports (GPIO) which can be used to drive up to 30 matrix LEDs (i. e. one per key). Each of the on-chip GPIO/LED driver is equipped with independent PWM source for enhanced visual effect such as dimming, and breathing. The SX8663 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.
