STMicroelectronics has recently launched a new automotive grade inertial sensing module called ASM330LHBG1, which integrates three-axis accelerometers and gyroscopes, making it highly suitable for use in the automotive industry. It is also equipped with a security software library designed specifically for functional security applications, which is extremely cost-effective. ASM330LHBG1 has successfully passed AEC-Q100 Level 1 certification, demonstrating its ability to operate stably under extreme temperature conditions (-40C to 125C), whether in direct sunlight during hot summer days or in high-temperature environments adjacent to the engine compartment.
The accuracy and reliability of this module have been widely recognized, suitable for vehicle navigation systems, body electronic systems, driving assistance systems, and more advanced autonomous driving technologies. Actual application scenarios include but are not limited to navigation systems, digital image stabilization technology, LiDAR and radar positioning, as well as applications in active suspension systems, door control, vehicle to vehicle communication (V2X), adaptive lighting, and motion control functions.
ASM330LHBG1 specifically introduces ST's machine learning core (MLC) and programmable state machine (FSM), enabling the execution of artificial intelligence (AI) algorithms even at extremely low power consumption, providing intelligent functionality. This IMU (Inertial Measurement Unit) uses the same pin interface and register configuration as other automotive IMUs in ST, ensuring a lower operating temperature range and a smooth technology upgrade path.
In addition, the module also has integrated temperature regulation function to ensure performance stability under various environmental conditions. At the same time, it provides six channels of synchronous output, greatly improving the accuracy of the heading calculation algorithm. The device also supports I 2 C. MIPI I3C and SPI serial interfaces, with programmable interrupt function, and 3KB of FIFO storage capacity further reduce the burden on the main processor.
The software part, after independent testing and verification, meets the ISO26262 standard. The redundant design achieved through two ASM330LHBG1 modules not only follows universal hardware standards, but also meets the requirements of contextualized security elements (SEooC) and meets the system certification standard of Automotive Safety Integrity Level B (ASIL B).
The software library also provides a complete set of configuration tools for verifying the normal working status of the sensing module before data collection and managing the data collection process. Each operation step is associated with an error code, and once a fault is detected, confirmation can be made. This dual sensor design achieves redundancy by comparing information from two different data sources, ensuring data consistency and reliability.
