    The SC7A20H is an acceleration sensor IC, which features abundant functions, low power, small size, and precision measurement.

    It communicates with MCU through I²C/SPI interface, the acceleration measurement data can be accessed in interrupt mode or inquiry mode. INT1 and INT2 provide many auto-detected interrupt signals which are suitable to many motion detection fields, interrupt source include  6D/4D direction detection interrupt signal, free fall detection interrupt signal, sleep and wake up detection interrupt signal and single/multi click detection interrupt signal. A high-precision calibration module is available within the IC to accurately compensate the senor’s offset error and gain error. It has dynamically user selectable full scales of ±2G/±4G/±8G/±16G and it is capable of measuring accelerations with output data rates from 1.56Hz to 4.434kHz.

    A self-test capability allows the user to check the functioning of the sensor in the final application, eliminating the complex turntable test.
