STMicroelectronics ISM330DHCX and LSM6DSRX iNEMO inertial measurement units

STMicroelectronics is extending the benefits of its motion-detection machine-learning core (MLC) technologies into industrial and high-end consumer applications with the ISM330DHCX and LSM6DSRX 6-axis iNEMO inertial measurement units (IMU). The MLC performs basic AI pre-processing of motion data using about 0.001 times the power a typical microcontroller (MCU) would consume to complete the same task. As a result, IMUs featuring this IP can offload the host MCU — a capability that is said to enable longer battery runtime, lower maintenance, and reduced size and weight in context-aware and motion-sensing devices.

The LSM6DSRX and ISM330DHCX are suitable for high-end consumer and industrial applications such as augmented/virtual reality, drone flight controls, dead-reckoning navigation systems, disk-antenna positioning systems, fleet management, container-tracking devices and dynamic inclinometers for industrial vehicles. The consumer-grade LSM6DSRX contains a 3-axis accelerometer and a 3-axis digital gyroscope with extended full-scale angular-rate range up to ±4000 dps and good performance in temperature and time. The industrial-grade ISM330DHCX comes with 10-year product-longevity assurance and is specified from -40 to 105°C, with embedded temperature compensation for stability.

In each device, the MLC interacts with integrated finite-state machine (FSM) logic, which can run simple repetitive algorithms like counting steps, hits or rotations at lower power than is said to be possible in a microcontroller. The FSM signals to the main controller after detecting a preset number of events or after a defined time has elapsed.
