Description

The STMPE16M31PX capacitive touchkey

controllers offer highly versatile and flexible

capacitive sensing capabilities in one single chip.

The devices integrate up to 16 capacitive sensing

channels which are highly sensitive and noise

tolerant. Eight independent PWM controllers allow

to control up to 16 LEDs with brightness control,

ramping and blinking capabilities. The I2C

interface supports up to 400 kHz communication

with the system host. A very wide dynamic range

allows most applications to work without

hardware tuning.

A single STMPE16M31PX device can be used to

implement a complete notebook multimedia

control bar with eight capacitive touchkeys,

proximity sensor with sensitivity up to 5 cm and

eight independently controlled LED.
