STMicroelectronicsLSM6DSV16BXTR

6-axis IMU with embedded sensor fusion, I3C, OIS/EIS for smart applications

he LSM6DSV is a high-end, low-noise, low-power 6-axis IMU, featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope, with a triple core for processing acceleration and angular rate data on three separate channels (user interface, OIS, and EIS) with dedicated configuration, processing, and filtering.

The LSM6DSV enables processes in edge computing, leveraging embedded advanced dedicated features such as a sensor fusion low-power (SFLP) algorithm and a finite state machine (FSM) for configurable motion tracking.

The LSM6DSV supports the adaptive self-configuration (ASC) feature, which allows the FSM to automatically reconfigure the device in real time based on the detection of a specific motion pattern, without any intervention from the host processor.
