N55T10 数据手册 ( 数据表 ) - Nuvoton Technology

GENERAL DESCRIPTION
The N55T10 is a general purpose capacitive touch sensor to co-work with other general microprocessors through serial interface. One N55T10 can support up to 10 sensor pads. Each pad equips with environment adaptive calibration function to prevent false trigger. The N55T10 features serial interface to communicate with master microprocessor to receive command /configuration from master and deliver touch sensor pad status to master chip. The N55T10 provides stand-by mode to minimize the power consumption and all touch sensor pads can be waked up under low stand-by current.
