ASM330LHHTR is an automotive‑grade 6‑axis inertial measurement unit (IMU) launched by STMicroelectronics.

Integrates a 3‑axis accelerometer and a 3‑axis gyroscope, designed for non‑safety‑related automotive applications.

Key Specifications

Package and Dimensions: 14‑pin LGA package with dimensions of 2.5 mm × 3.0 mm × 0.83 mm, suitable for installation in space‑constrained areas.

Operating Temperature: Wide temperature range from ‑40 °C to +105 °C, meeting automotive environmental requirements.

Measurement Ranges:‑ Accelerometer: Four selectable full‑scale ranges: ±2 g / ±4 g / ±8 g / ±16 g‑ Gyroscope: Six selectable full‑scale ranges from ±125 dps to ±4000 dps

Interface Types: Supports I2C, SPI and I3C serial interfaces for convenient communication with host processors.

Power Consumption Features: Standby current as low as 3 μA; typical current consumption around 1.3 mA in high‑performance mode, helping extend battery life.

Certification: AEC‑Q100 automotive‑grade qualified, complying with automotive reliability standards.

Other Features: Built‑in 3 KB FIFO buffer; supports smart programmable interrupts and six‑channel synchronous output.

Main Applications

Automotive Applications: Inertial dead reckoning, V2X communication, telematics, electronic toll collection systems, anti‑theft systems, crash detection and crash reconstruction.

Motion Detection: Event detection including free‑fall, 6D orientation, activity/in‑activity monitoring.

Other Scenarios: Driving comfort adjustment, vibration monitoring and compensation, sensor‑fusion implementations.
