STMicroelectronics LIS2DUX12 Ultra Low-Power Accelerometer

STMicroelectronics LIS2DUX12 Ultra Low-Power Accelerometer is a smart, digital, 3-axis linear accelerometer. The STMicroelectronics LIS2DUX12 MEMS and ASIC are designed to combine the lowest current consumption possible with features like always-on anti-aliasing filtering and a finite state machine (FSM). Other features include a 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.
