STMicroelectronics launches a vehicle gauge artificial intelligence inertial measurement unit, suitable for continuous sensing applications with ambient temperatures up to 125 degrees Celsius

    The ASM330LHHXG1 Inertial Measurement Unit (IMU) of STMicroelectronics integrates internal artificial intelligence and improved low-power operating mode of the sensor, and extends the maximum operating temperature to 125 ° C, ensuring that the sensor can work reliably in harsh environments.

    The new IMU of STMicroelectronics integrates a three-axis accelerometer and a three-axis gyroscope, with a working current of less than 800 µ A when both sensors are operating simultaneously. The low-power characteristic can reduce the system power budget and promote the promotion and use of the product in always aware applications. By utilizing the built-in machine learning core (MLC) and finite state machine (FSM), artificial intelligence within sensors can reduce the workload of the main processor, making event detection and classification work shorter and more energy-efficient. The wide temperature range allows intelligent sensors containing ASM330LHHXG1 to be flexibly deployed in harsh conditions, including near the engine, direct sunlight, or when the dissipated power on the board may raise the temperature above standard operating temperature.

    By integrating MLC and FSM, ASM330LHHXG1 can be used for applications that require fast response, certainty, and low power consumption, including navigation assistance and remote information processing, anti-theft, collision detection, and motion activation functions.

    With the help of Unico GUI and AlgoBuilder software tools, as well as the MEMS sensor adapter board (STEVAL-MKI243A), the MEMS ecosystem of STMicroelectronics can help accelerate application evaluation, prototype design, and product development based on ASM330LHHXG1. In addition, engineers can find ready-made application code examples in ST‘s GitHub repository. The MLC library includes use cases for tilt, traction, and vehicle status detection. The FSM library offers more inspiring solutions, including motion/still detection and jitter detection.

    Although IMU has a dual operating mode, allowing designers to optimize data update rate and power consumption, the time and temperature drift stability of accelerometers and gyroscopes are excellent. The full range of the accelerometer can be set to ± 2/± 4/± 8/± 16g, and the angular rate of the gyroscope can be set to ± 125, ± 250, ± 500, ± 1000, ± 2000 or ± 4000 degrees per second.

    ASM330LHHXG1 is an AEC-Q100 certified product that has been mass-produced and is currently packaged in a 14 lead plastic grid array (LGA) with ultra molded pressure.
