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 fast real-time response and sophisticated functions with low system power demand.
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 in an application processor or cloud-based AI. Demonstration boards and free software example libraries are available to simplify application development. Functions available include vehicle-stationary detection, attitude and heading reference, altitude estimation, car-tow detection, and crash detection.
Leveraging ST’s micro-electro-mechanical systems (MEMS) technology, the automotive-qualified ASM330LHHX houses a 3-axis accelerometer and 3-axis gyroscope in a 2.5mm x 3mm x 0.83mm outline. The 6-axis module provides movement and attitude sensing for functions including vehicle positioning and digital stabilisation.
