STM LIS2DUX12 is an Ultralow-Power Accelerometer with Anti-aliasing and AI

Written by Stephen Vicinanza

STM LIS2DUX12 is an ultralow-power accelerometer with anti-aliasing and AI. Although released in November 2022, the LIS2DUX12 from STMicroelectronics (STM) was just showcased at Sensors Converge 2023.

The STM LIS2DUX12 is a smart, digital, 3-axis linear accelerometer whose MEMS and ASIC have been expressly designed for the lowest power consumption. Features include always-on anti-aliasing filtering, finite state machine (FSM), and machine learning core (MLC) that has an adaptive self-configuration (ASC).

The FSM and MLC with ASC offer always-on, edge processing capabilities. The sensor’s MIPI I3C slave interface and embedded 128-level FIFO buffer complete a set of features that make the accelerometer a reference in terms of system integrations. This is from the point of view of the bill of materials, power consumption, and processing.

The accelerometer has a dedicated internal engine to process motion and acceleration detection including free-fall, single/double/triple-tap recognition, activity/inactivity, wake-up, and 6D/4D orientation.

The LIS2DUX12 has a user-selectable full scale of ±2g/±4g/±8g/±16g. It is also capable of measuring acceleration with output data rates from 1.6Hz and 800Hz.
