MSKSEMI LIS2DTW12TR-MS

This device is a high-precision digital triaxial accelerometer IC featuring rich functionality, low power consumption, compact form factor, and accurate measurements. The chip communicates with an MCU via I²C/SPI interface, and acceleration measurement data can be retrieved through interrupts or polling. The INT1 and INT2 interrupt pins provide multiple internally auto-detected interrupt signals, suitable for various motion detection scenarios; interrupt sources include 6D/4D orientation detection, free-fall detection, sleep and wake-up detection, and single/double-tap detection. An on-chip high-precision calibration module compensates accurately for sensor offset and gain errors. Four selectable full-scale measurement ranges are available — ±2G, ±4G, ±8G, and ±16G — for flexible external acceleration measurement, with an output data rate selectable from 1.56 Hz to 4.27 kHz. The built-in self-test function allows customers to verify system functionality during system-level testing, eliminating the need for complex turntable testing.
