5 V 98 μA in active mode, 60 μA in idle mode Dual interrupt output pin I2C interface (up to 400 kHz) 7 kV HBM ESD protection Idle and sleep mode for low power operation Advanced data filtering (AFS) Environment tracking calibration (ETC) Individually adjustable touch variance (TVR) setting for all channels Adjustable environmental variance (EVR) for optimal calibration QFN40 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 capacit...
