12 channel touch key controller

Features

µA in active mode, 60µA in idle mode

setting for all channels

optimal calibration

Description

The STMPE1208S is a GPIO 12 channel

capacitive touch key sensor able to interface a

Main Digital ASIC via the two-line bidirectional

bus (I2C). It senses changes in capacitance using

a fully digital architecture, giving fast and accurate

results at very low power consumption. Automatic

Impedance Calibration ensures that changes in

environment will never affect the correct operation

of the capacitive touch keys.
