The ASM330LHB is equipped with dedicated software to solve the design challenges of ASIL B functional safety applications.
The module consists of a three-axis digital accelerometer and a three-axis digital gyroscope. It adopts a car-level design and provides six-channel synchronous output. The excellent inertial measurement accuracy can improve the positioning accuracy of the car in the relevant environment. The module supports ADAS advanced driver assistance system or vehicle-to-everything (V2X) communication, which helps important perception systems such as radar, lidar, and visual cameras maintain stable performance, and assists L2+ level semi-autonomous driving applications. In addition, the module can be used for various body control functions.
Automotive 6-axis inertial module
The ASM330LHB, with its accompanying software engine, addresses the growing demand from carmakers for automotive systems that comply with Level B safety integrity requirements. Using two ASM330LHB sensor modules to design a fail-safe redundancy mechanism can quickly restore environmental perception data for driving assistance systems such as lane keeping, emergency braking, cruise assist, and semi-autonomous driving. The ASIL B-level software library is developed in accordance with the automotive functional safety standard ISO 26262 and has been tested and certified by the third-party independent certification body TÜV SÜD. By implementing dedicated safety mechanisms, including data integrity and measurement correctness, the software library ensures automotive systems comply with ASIL B requirements.
In addition to making driving safer, the ASM330LHB has very high application flexibility, allowing users to experience a smarter lifestyle, for example, embedded intelligence helps to add new car services, for example, when the driver leaves the car Indicates the status of the car. Running on an integrated machine learning core (MLC) with an operating current of only a few microamps, machine learning algorithms can detect vehicle safety events such as theft, lifting, towing, and collisions. Additionally, simultaneous monitoring of multiple thresholds keeps the internal finite state machine (FSM) in optimal conditions to detect vehicle motion or stationary, vibrating or unstable states.
The module's accelerometer and gyroscope have excellent time and temperature zero-drift stability, very low noise, and an overall bias instability of up to 3°/hour. The ASM330LHB has an extended nominal temperature range of -40°C to 105°C and features multiple operating modes that allow designers to optimize data update rates and power consumption.
The ASM330LHB is AEC-Q100 qualified in a 2.5mm x 3.0mm 14-pin VFLGA package and is in production now.
