Description：

The ASM330LHBG1 is a 6-axis IMU that offers ASIL B compliance if used in 

conjunction with a certified software library and features a 3-axis digital 

accelerometer and a 3-axis digital gyroscope with an extended temperature range up 

to +125°C.

A safety manual and a software library, certified according to ISO 26262:2018, are 

provided to support the development of applications using the ASM330LHBG1 and 

targeting ASIL B requirements.

ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes to serve both the automotive and consumer market. The ASM330LHBG1 is AEC-Q100 compliant and industrialized through a dedicated MEMS production flow to meet automotive reliability standards. All the parts are fully tested with respect to temperature to ensure the highest quality level.

The sensing elements are manufactured using ST’s proprietary micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit, which is trimmed to better match the characteristics of the sensing element.

The ASM330LHBG1 has a full-scale acceleration range of ±2/±4/±8/±16 g and a wide angular rate range of  ±125/±250/±500/±1000/±2000/±4000 dps that enables its usage in a broad range of automotive applications.

The device supports dual operating modes: high-performance mode and low-power mode.

All the design aspects of the ASM330LHBG1 have been optimized to reach superior output stability, extremely low noise, and full data synchronization to the benefit of sensor-assisted applications like dead reckoning and sensor fusion.

The ASM330LHBG1 is available in a 14-lead plastic, land grid array (LGA) package.
