STMicroelectronics ISM330DLC 6-axis inertial measurement unit

Click2Contact

The ISM330DLC 6-axis IMU (inertial measurement unit) extends STMicroelectronics’ family of ultralow-power MEMS sensors for industrial applications.

Containing a 3-axis accelerometer and a 3-axis gyroscope with user-selectable full-scale up to ±16g and ±2000 dps respectively, the IMU provides high measurement resolution and smart energy-saving features to enable long-lasting, battery-powered industrial devices. Suitable for applications such as Industrial IoT systems, robots, drones, platform stabilisers and telematics, its wide accelerometer bandwidth up to 3 kHz also allows use in vibration-monitoring and compensation systems.

The product consumes just 0.5 mA in normal combination mode and 0.75 mA in high-performance mode. With a large integrated FIFO that lets the host system retrieve data efficiently, as well as smart features and interrupts including tilt detection, free-fall, wake-up, 6D/4D orientation, click and double-click, the device enables power-conscious application design to achieve additional energy savings. There is also a sensor-hub feature for efficiently collecting data from additional external sensors.

Extensive industrial-grade design features are built in, including a dedicated configurable low-latency signal-processing path, low noise and filtering optimised to ensure closed-loop control stability. The signal path can be independently configured to make gyroscope or accelerometer data available through an auxiliary SPI interface.

As a richly featured device architected for stability and robustness, the IMU also contains a temperature sensor and built-in self-test both for the gyroscope and accelerometer.
