Description

The STMPE16M31 and STMPE24M31 capacitive

touchkey controllers offer highly versatile and

flexible capacitive sensing capabilities in one

single chip.

The devices integrate up to 24 capacitive sensing

channels which are highly sensitive and noise

tolerant. Two units of hardwired ratiometric

engines enable the implementation of a

slider/wheel without external computations. 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 STMPE24M31 device can be used to

implement a complete notebook multimedia

control bar with eight capacitive touchkeys, an 8-

channel slider with 256 steps resolution and eight

independently controlled LED.
