STMicroelectronics (ST), a global semiconductor company supporting a wide range of electronic applications and customers, is launching a new automotive inertia module with improved accuracy, enhancing reliability in vehicle navigation, body electronics, and autonomous driving systems.

ST announced on the 29th that it has released the ASM330LHBG1 automotive 3-axis accelerometer and 3-axis gyroscope module, along with a safety software library that supports cost-effective solutions for functional safety applications.

The ASM330LHBG1 is AEC-Q100 Class 1 certified for an ambient operating temperature range of -40°C to 125°C, making it suitable for use in engine compartments or areas exposed to direct sunlight.

This module provides high accuracy and reliability in vehicle navigation, body electronics, driver assistance systems, and highly automated driving systems.

Generally, it can be used to support precision positioning for navigation systems, digital stabilization cameras, LiDAR and radar, active suspension, door modules, V2X (Vehicle-to-Everything) applications, adaptive lighting, and motion-activated functions.

The ASM330LHBG1 is equipped with ST's MLC (Machine-Learning Core) and FSM (Finite State Machine) to execute AI (Artificial Intelligence) algorithms, providing smart features with very low power consumption.

This 6-axis IMU (Inertial Measurement Unit) can be seamlessly upgraded with the same register map configuration and pin-to-pin package compatibility as ST's existing automotive 6-axis IMU.

In addition, this module features built-in temperature compensation to ensure stability under a wide range of operating conditions and provides 6-channel synchronized outputs to improve the accuracy of dead-reckoning algorithms. Furthermore, it includes a 3KB FIFO that allows for easy management of sensor data to minimize the load on the host process, as well as I²C, MIPI I3C, and SPI serial interfaces and smart programmable interrupts.

The software, certified through independent testing, complies with ISO26262 and supports a redundant design suitable for safety functions using two ASM330LHBG1 modules. This combination of general-purpose hardware, which meets SEooC (Safety Element out of Context), supports system certification up to ASIL B (Automotive Safety Integrity Level B).

This library provides software that configures the sensing module, verifies proper operation before starting data collection, and processes incoming data from the sensing module. Each of these steps is associated with an error code that identifies the fault when it is detected. This solution, consisting of two identical sensors, provides a redundant design while verifying the consistency of data from two different sensing sources.

The ASM330LHBG1 is currently being produced in a 14-lead, 2.5mm x 3mm VFLGA plastic LGA (Land Grid Array) package. The budget price is $9.40 for a purchase of 1,000 units.
