ST delivers advanced context-aware sensors in ST Sustainable Technology framework
STMicroelectronics’ newest miniature motion sensors feature enhanced precision for accurate event reconstruction while meeting the most stringent sustainable-materials standards.
The LSM6DSK320X is a compact, low-power, high-performance IMU that integrates a 3-axis digital low-g accelerometer with selectable full scale up to ±16 g, a 3-axis digital high-g accelerometer up to ±320 g, and a 3‑axis digital gyroscope. Its advanced architecture processes acceleration and angular-rate data through four independent channels: User Interface (UI), OIS, EIS, and high-g acceleration.
Designed for demanding motion-sensing applications, the LSM6DSK320X enables intense movement tracking, shock and concussion monitoring, and other high-dynamic use cases.
The device features a new gyroscope architecture with a fully differential readout chain and enhanced mechanical symmetry, delivering outstanding vibration immunity and resilience to external disturbances. It also supports edge AI functions through a finite state machine (FSM) for configurable motion detection and a machine learning core (MLC) for context awareness, enabling intelligent features for personal electronics, IoT, sports and wearables, and drone applications.
To optimise power consumption, the LSM6DSK320X includes adaptive self-configuration (ASC), which automatically adjusts sensor settings in real time based on detected motion patterns or MLC events, without host intervention. The digital subsystem also integrates ST’s sensor fusion low-power (SFLP) technology for spatial orientation.
In addition, a dedicated high-g acceleration sensor with an independent channel and dedicated filtering ensures reliable shock detection, making the device well suited for sports, concussion detection, impact detection, emergency call, and drone applications.
The new IMUs are supported within the ST MEMS Studio development environment. The STEVAL-MKI257A adapter board for the LSM6DSK320X and STEVAL-MKI258KA adapter board for the ISM6HGK256X will be available in the eSTore and from distributors by November 2026.
The LSM6DSK320X for consumer applications operates over a broad temperature range, from -40°C to +85°C. The industrial-grade ISM6HGK256X handles temperatures from -40°C to +105°C and is included in ST’s 10-year longevity program that assures long-term component availability.
