STMPE321, 3-channel capacitive touch key controller
The STMPE321 is a 3-channel capacitive touch key controller.
Capacitance measurement is implemented in fully optimized hardware.
All 3 I/Os can be configured via an I2C bus to function as either capacitive touch key, or as GPIOs (general purpose I/O).
Applications * * * Mobile phones a
