Product Descriptions

SC7A20 is a high-precision 12 bit 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 I 2 C/SPI interface, and acceleration measurement data is obtained through interrupt or query methods. INT1 and INT2 interrupt pins provide various internal automatic detection interrupt signals, suitable for various motion detection scenarios. The interrupt sources include 6D/4D direction detection interrupt signals, free fall detection interrupt signals, sleep and wake-up detection interrupt signals, and single click and double-click detection interrupt signals. The chip is equipped with a high-precision calibration module to accurately compensate for sensor misalignment and gain errors. Four adjustable full range measurement ranges of ± 2G, ± 4G, ± 8G, and ± 16G are available for flexible measurement of external acceleration. The output data rate can be selected between 1HZ and 400Hz.

The built-in self-test function of the chip allows customers to detect system functions during system testing, eliminating the need for complex turntable testing. The chip has built-in product tilt calibration function, which compensates for tilt caused by surface mount and board installation without occupying system resources, and system file upgrades do not affect sensor parameters.
