ADVANCED MUNICATIONS & SENSING
GENERAL DESCRIPTION
The SX8662 is an ultra low power, fully integrated 12-channel solution for capacitive touch-button matrix applications (up to 36 keys). Unlike many capacitive touch solutions, the SX8662 Features dedicated capacitive sense inputs (that requires no external ponents) in addition to 8 general purpose I/O ports (GPIO) which can be used to drive up to 36 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.
