Additional Infomation About Product

STMPE1208S S-Touch 12-channel capacitive touchkey controller Features 12 touchkey capacitive sensor inputs 12-bit general purpose input/output (GPIO) Operating voltage 3.0 5.5 V 98 A in active mode, 60 A in idle mode Dual interrupt output pin 2 I C 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) QFN40 Individually adjustable touch variance (TVR) setting for all channels Adjustable environmental variance (EVR) for optimal calibration Applications Description Notebook computers The STMPE1208S is a 12-channel GPIO capacitive Monitors touchkey sensor able to interface a main digital ASIC 2 via the two-line bidirectional bus (I C). It senses Set-top boxes changes in capacitance using a fully digital Televisions architecture, giving fast and accurate results at very low Portable media players and game consoles power consumption. Automatic impedance calibration Mobile and smart phones ensures that changes in environment will never affect the correct operation of the capacitive touchkeys.
