Description

The STMPE1208S is a 12-channel GPIO

capacitive touchkey 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 touchkeys.
