STMPE1208S Datasheet (STMicroelectronics)

STMPE1208S, Xpander Logic

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.
