STMicroelectronics ASM330LHH Automotive 6-axis Inertial Module

ASM330LHH Automotive 6-axis Inertial Module is a compact System-in-Package (SiP) featuring a 3D digital accelerometer and a 3D digital gyroscope. This six-axis Inertial Measurement Unit (IMU) is designed for super-high-resolution motion tracking in advanced vehicle navigation and telematics applications.

Serving demands for continuous, accurate vehicle location to support automated services, the ASM330LHH lets advanced dead-reckoning algorithms calculate precise positions from sensor data if satellite signals are blocked. This often happens in urban canyons, tunnels, covered roadways, parking garages, or dense forests. The advanced, low-noise, temperature-stable design of the ASM330LHH enables dependable telematics services such as e-tolling, tele-diagnostics, and e-Call assistance. Precision inertial data in six axes also meets the needs of advanced automated driving systems.

All the design aspects of the ASM330LHH have been optimized to reach superior output stability, extremely low noise, and full data synchronization to benefit sensor-assisted applications like dead reckoning and sensor fusion.

The ASM330LHH is offered in a 14-lead plastic Land Grid Array (LGA) package, is AEC-Q100 qualified, and is ECOPACK, RoHS, and "Green" compliant.
