Product Overview

The LIS2DUXS12 is a smart, digital, 3-axis linear accelerometer designed for ultralow power consumption. It features an always-on anti-aliasing filter, a finite state machine (FSM), a machine learning core (MLC) with adaptive self-configuration (ASC), and an analog hub/Qvar sensing channel. This accelerometer offers advanced edge processing capabilities, system optimization through its analog hub, and efficient system integration with its MIPI I3C interface and embedded FIFO buffer. It supports user-selectable full scales of 2g/4g/8g/16g and a wide range of output data rates from 1.6 Hz to 800 Hz. The device includes embedded digital functions for motion and acceleration detection, such as free-fall, wake-up, tap recognition, activity/inactivity, and orientation detection. It is available in a small LGA package and operates over an extended temperature range.
