Description:

The LSM6DSK320X is a high-end, low-noise, low-power, small IMU featuring a 3-axis digital low-g accelerometer at ±16 g, a 3-axis digital high-g accelerometer at ±320 g, and a 3-axis digital gyroscope. It offers the best IMU sensor architecture for processing acceleration and angular rate data on four separate channels (User Interface, OIS, EIS, and high-g accelerometer). This IMU enables a new range of applications targeting intense movement tracking, concussion monitoring, and more.The LSM6DSK320X adopts a new gyroscope design with a fully differential reading chain and enhanced mechanical symmetry for outstanding vibration immunity and resilience to external perturbations. The device supports edge AI computing, leveraging a finite state machine (FSM) for configurable motion tracking and a machine learning core (MLC) for context awareness, with exportable AI features for personal electronics, IoT, 

sports and wearable devices, and drone applications.The LSM6DSK320X features adaptive self-configuration (ASC) to optimize power consumption. The sensor can automatically adjust its settings in real time upon detecting a specific motion pattern or signal from the MLC, without intervention from the host processor. The digital circuitry also includes ST’s sensor fusion low-power (SFLP) technology for spatial orientation.The device embeds a dedicated accelerometer sensor with an independent channel and filtering for high-g acceleration detection, perfectly matching shock requirements for sports, concussion detection, shock detection, emergency call and drone applications.
