New inertial measurement unit (IMU) for automotive applications launches by STMicroelectronics. The new ST ASM330LHHXG1 inertial measurement unit(IMU) touted to combine in-sensor AI with enhanced low-power operation and 125°C operating temperature range for reliability in harsh environments.
Key Features of The New ST inertial measurement unit (IMU) Includes:
- 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.
ST’s MEMS ecosystem helps accelerate evaluation, prototyping and development with the ASM330LHHXG1, - Leverages Unico-GUI and AlgoBuilder tools and MEMS-sensor adapter boards (STEVAL-MKI243A).
Also, engineers can find ready-to-use application examples at ST’s GitHub repository area. The MLC repository contains use cases such as tilt, towing, and vehicle-status detection. The FSM repository has further inspiration including motion/stationary detection and shake detection.
While the IMU has dual operating modes that let designers optimize the data-update rate and power consumption, the accelerometer and gyroscope maintain high stability over time and temperature. The accelerometer has a selectable full-scale range of ±2/±4/±8/±16g, while the gyroscope’s angular rate can be set to ±125, ±250, ±500, ±1000, ±2000, or ±4000 degrees per second.
Availability
The ASM330LHHXG1 is AEC-Q100 qualified and in production now. It is available in an over-molded 14-lead plastic land grid array (LGA) package. Pricing starts from $8.99 for orders of 1,000 pieces.
