STMicroelectronics has released the ASM330LHB automotive-qualified MEMS inertial-sensing module, which provides accurate measurements for a wide variety of vehicle functions. With the dedicated software provided, ASM330LHB also addresses functional-safety applications up to ASIL B1.

ASM330LHB contains a 3-axis digital accelerometer and 3-axis digital gyroscope that provide a six-channel synchronized output. The module’s high-accuracy inertial measurements are used to improve the precise positioning of a vehicle.

The accelerometer and gyroscope maintain high stability over time and temperature and have very low noise for an overall bias instability of 3°/hour. Specified over the extended temperature range, -40°C to 105°C, the ASM330LHB has multiple operating modes that let designers optimize the data-update rate and power consumption.

ASM330LHB can support advanced driver assistance systems or vehicle-to-everything communication, as well as help stabilize sensing systems such as radar, lidar and cameras, and assist semi-automated driving applications up to L2+. Additionally, ASM330LHB can be used to enable a variety of functionalities in the body of a vehicle.

ASM330LHB was developed with the automotive functional-safety standard ISO 26262 — the ASIL B compatible software library has been certified independently by TÜV SÜD. By implementing dedicated safety mechanisms, including data integrity and accuracy, the library ensures compliance with ASIL B automotive systems.

With the companion software engine, the ASM330LHB supports the growing adoption of automotive systems that require safety integrity up to level B. The combination of two ASM330LHB sensor modules for fail-safe redundancy delivers resilient contextual data for driver-assistance applications such as lane centering, emergency braking, cruise assistance and semi-automated driving.

ASM330LHB is AEC-Q100 qualified and in production now in a 2.5 mm x 3.0 mm 14-lead VFLGA package.
