en.Wedoany.com Reported - STMicroelectronics has introduced an automotive-qualified inertial measurement unit (IMU), the ASM330LHHG1, which operates across a wide temperature range from -40°C to 125°C. It integrates a 3-axis accelerometer and a 3-axis gyroscope, making it suitable for applications such as navigation, telematics, and agricultural vehicles.

Designed for navigation, electronic toll collection, V2X communication, anti-theft, collision reconstruction, and vibration monitoring in cars, trucks, as well as industrial and agricultural vehicles, this IMU features built-in temperature compensation. It supports dead reckoning, GNSS fusion, and motion data correlation, and provides six-channel synchronous output. In terms of measurement range, the accelerometer reaches up to ±16g, while the gyroscope covers a range from ±125dps to ±4000dps. The device offers both high-performance and low-power operating modes, supports I²C, MIPI I3C®, and SPI communication interfaces, and uses a 3KB FIFO to reduce the main processor load and overall power consumption. The ASM330LHHG1 complies with the AEC-Q100 automotive reliability standard and is packaged in a 2.5 mm x 3.0 mm LGA-14L form factor.
