SX8662 - Capacitive Button Matrix (up to 36) Controller
SEMTECH
General Description
The SX8662 is an ultra low power, fully integrated 12-channel solution for capacitive touch-button matrix applications (up to 36 keys).
Key Features
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 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. The SX8662 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.

ADVANCED COMMUNICATIONS & 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 components) 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. The SX8662 includes a capacitive 10 bit ADC analog int
