STMicroelectronics STMPE1208S
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.| Part No. | STMPE1208S |
