STMicroelectronics ASM330LHB Automotive 6-Axis Inertial Module

STMicroelectronics ASM330LHB High-Accuracy Automotive 6-Axis Inertial Module is a system-in-package incorporating a 3-axis digital accelerometer and a 3-axis digital gyroscope. A safety manual and a software library, certified according to ISO26262:2018, are offered to support the development of applications utilizing the ASM330LHB and targeting ASIL-B requirements.

The STM ASM330LHB is AEC-Q100 compliant and industrialized through a dedicated MEMS production flow to meet automotive reliability standards. All the parts are thoroughly tested concerning temperature to guarantee the highest quality. The sensing elements are manufactured utilizing ST’s proprietary micromachining processes. At the same time, the IC interfaces are designed using CMOS technology that permits the design of a dedicated circuit, which is trimmed to match the attributes of the sensing element better.

The ASM330LHB includes a full-scale acceleration range of ±2/±4/±8/±16g and a wide angular rate range of ±125/±250/±500/±1000/±2000/±4000dps that allows its usage in a broad range of automotive applications. The device supports dual operating modes, a high-performance mode, and a low-power mode. All the design elements of the ASM330LHB have been optimized to reach exceptional output stability, extremely low noise, and complete data synchronization to benefit sensor-assisted applications like dead reckoning and sensor fusion.

The ASM330LHB is housed in a 14-lead plastic land grid array (LGA) package with an extended temperature range of up to +105°C.
