STMicroelectronics introduces AI-enabled automotive inertial measurement unit for always-aware applications up to 125°C

STMicroelectronics’ ASM330LHHXG1 inertial measurement unit (IMU) for automotive applications combines in-sensor AI with enhanced low-power operation and 125°C operating temperature range for reliability in harsh environments.

ST’s new automotive IMU contains a 3-axis accelerometer and 3-axis gyroscope and draws less than 800µA with both sensors running, cutting the system power budget and encouraging use in always-aware applications. In-sensor AI leverages the built-in machine-learning core (MLC) and finite state machine (FSM), offloading the host processor and enabling low-latency, energy-efficient event detection and classification. The extended temperature range gives flexibility to deploy smart sensors containing the ASM330LHHXG1 in harsh locations including near engine components, in direct sunlight, or whenever on-board power dissipation might increase the temperature above standard operating levels.

With the integrated MLC and FSM, the ASM330LHHXG1 handles applications that need fast and deterministic response with minimal power demand. These include navigation assistance and telematics, theft prevention, impact detection, and motion-activated functions (more info).
