The SC7A20H is a high-precision, digital three-axis accelerometer sensor chip with enhanced functionality, lower power consumption, and a smaller footprint for more accurate measurements. It communicates with MCUs via IC/SPI interfaces, providing acceleration data through interrupts or polling. The INT1 and INT2 interrupt pins offer multiple automatic internal detection interrupt signals suitable for various motion detection scenarios, including 6D/4D orientation detection, free-fall detection, sleep and wake-up detection, and single/double-tap detection. The chip features a built-in high-precision calibration module for precise compensation of sensor offset and gain errors. It offers four adjustable full-scale measurement ranges (2G, 4G, 8G, 16G) and selectable output data rates between 1.56Hz and 4.27kHz. A self-test function allows for system testing without complex turntable setups.
