Six-Axis IMU Is Industry Ready

STMicroelectronics’ ISM330DLC six-axis inertial measurement unit (IMU) extends the company’s family of ultra-low power MEMS sensors for industrial applications. Containing a three-axis accelerometer and a three-axis gyroscope with user-selectable full-scale up to ±16g and ±2000dps respectively, the ISM330DLC 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 stabilizers, and telematics, its accelerometer bandwidth up to 3 kHz also allows use in vibration-monitoring and compensation systems.

 

The ISM330DLC consumes 0.5 mA in normal combination mode and 0.75 mA in high-performance mode. Other features include a large integrated FIFO that lets the host system retrieve data efficiently, smart features and interrupts including tilt detection, free-fall, wakeup, 6D/4D orientation, click, and double-click. There is also a sensor-hub feature for collecting data from additional external sensors.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

Industrial-grade design features include a dedicated configurable low-latency signal-processing path, low noise, and filtering optimized 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. The ISM330DLC also contains a temperature sensor and built-in self-test both for the gyroscope and accelerometer.

 

Available now in a 2.5 mm x 3 mm x 0.83 mm plastic land-grid array (LGA) system-in-package, pricing starts at $2.90 each/1000. Greater illuminations are readily available from the ISM330DLC datasheet.
