Description
The STMPE16M31PX and STMPE24M31PX
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. 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 STMPE24M31PX 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.
