Introduction

The LIS2DUx12 is a smart, digital, 3- axis linear accelerometer whose MEMS and ASIC have been expressly designed to combine the lowest supply current possible with features such as always- on antialiasing filtering, a finite state machine (FSM) and machine learning core (MLC) with adaptive self- configuration (ASC). The FSM and MLC with ASC deliver outstanding always- on, edge processing capabilities to the LIS2DUx12. The LIS2DUx12 MIPI I3C slave interface and embedded 128- level FIFO buffer complete a set of features that make this accelerometer a reference in terms of system integration from a standpoint of the bill of materials, processing, or power consumption. The LIS2DUx12 has user- selectable full scales of ± 2g / ± 4g / ± 8g / ± 16g and is capable of measuring accelerations with output data rates from 1.6Hz to 800Hz. The device has a dedicated internal engine to process motion and acceleration detection including free- fall, wakeup, single/double/triple- tap recognition, activity/inactivity, and 6D/4D orientation. The LIS2DUx12 is available in a small thin plastic, land grid array (LGA) package, and it is guaranteed to operate over an extended temperature range from - 40℃ to +85℃.
