SC7A20H high-precision three-axis load force acceleration tilt Angle sensor module IIC/SPI transmission

Product Introduction  

SC7A20H is a high-precision digital three-axis acceleration sensor chip with richer built-in functions, lower power consumption, smaller size and more accurate measurement.

The chip communicates with the MCU through the IC/SPI interface, and the acceleration measurement data is obtained in interrupt mode or query mode. The INT1 and INT2 interrupt pins provide a variety of internal automatic detection interrupt signals to adapt to a variety of motion detection occasions. The interrupt sources include 6D/4D direction detection interrupt signals, free fall detection interrupt signals, sleep and wake-up detection interrupt signals, single-click and double-click detection interrupt signals. The chip has a built-in high-precision calibration module to accurately compensate for the sensor's offset error and gain error. Four adjustable full-scale measurement ranges of ±2G, ±4G, ±8G and ±16G can flexibly measure external acceleration, and the output data rate can be selected between 1.56HZ and 4.434kHz.

The chip's built-in self-test function allows customers to detect system functions during system testing, eliminating complex turntable testing.
