LSM6DSO in ST LSM / LIS IMU & Accelerometers Family
The LSM6DSO is a high-performance 6-axis inertial measurement unit (IMU) from STMicroelectronics, integrating a 3-axis digital accelerometer and a 3-axis digital gyroscope. Designed for battery-constrained applications, it operates with ultra-low power consumption as low as 0.55 mA in high-performance mode. It features an embedded Machine Learning Core (MLC) and Finite State Machine (FSM) to offload sensor data processing from the host microcontroller, making it a benchmark component for sophisticated motion tracking in modern consumer and industrial electronics.
Variants in This Sub-Family
Variants within the LSM6DSO sub-family primarily differentiate by interface support and specialized functional blocks. The LSM6DSOX includes the Machine Learning Core, whereas the base LSM6DSO focuses on standard motion processing. Specialized versions like the LSM6DSO32X offer an expanded full-scale acceleration range up to ±32g. Some variants are automotive-qualified (A-grade) or optimized for specific stability requirements in OIS applications, ensuring pin-to-pin compatibility across diverse performance tiers.
