LIS2DUXS12TR, STMicroelectronics 3-Axis Surface Mount Accelerometer, LGA, 12-Pin

Ultra-low-power 3-axis digital smart accelerometer with AAF and Qvar

The STMicroelectronics smart, digital, 3-axis linear accelerometer whose MEMS and ASIC have been expressly designed to combine the lowest current consumption possible with features such as always-on anti-aliasing filtering, a finite state machine (FSM) and machine learning core (MLC) with adaptive self-configuration (ASC), and an analog hub / Qvar sensing channel. The FSM and MLC with ASC deliver outstanding always-on, edge processing capabilities, while the analog hub / Qvar sensing channel defines a new degree of system optimization. It has a dedicated internal engine to process motion and acceleration detection including free-fall, wake-up, single/double/triple-tap recognition, activity/inactivity, and 6D/4D orientation.
