STMicroelectronics’ ASM330LHHX inertial measurement unit (IMU) moves smart driving another step closer to high levels of automation with its machine learning (ML) core. The ML core enables real-time response and complex functions with low system power demand.
Leveraging ST’s micro electromechanical systems (MEMS) technology, the automotive-qualified ASM330LHHX houses a 3-axis accelerometer and 3-axis gyroscope in a 2,5 x 3 x 0,83 mm package. The 6-axis module provides movement and attitude sensing for functions including vehicle positioning and digital stabilisation. It has a full-scale acceleration range of ±2/±4/±8/±16 and a wide angular rate range of ±125/±250/±500/±1000/±2000/±4000 dps that enables its usage in a broad range of automotive applications.
The ML core, a hardwired processing engine, runs AI algorithms directly on the sensor, ensuring extremely low latency between sensing an event and the vehicle’s response. This enables sophisticated real-time performance that demands far lower system energy and computing power than a solution embedded on an application processor or cloud-based AI. Functions available include vehicle-stationary detection, attitude and heading reference, altitude estimation, car-tow detection and crash detection.
The ASM330LHHX has two operating modes, including low-power mode for running always-on applications like telematics, anti-theft systems, motion-activated functions, and vibration monitoring and compensation. When operated in low-power mode, current consumption is less than 800 µA with both the accelerometer and gyroscope running. There is also a high-performance mode for applications that demand the highest accuracy and lowest latency, including precise positioning, vehicle-to-everything (V2X) communication, and impact detection and crash reconstruction.
ST’s proven MEMS fabrication processes ensure excellent sensor stability and low noise, and the module maintains high accuracy over an extended operating temperature range of -40°C to 105°C.
