STMicroelectronics ASM330LHHX Auto 6-axis ML Core Inertial Module

STMicroelectronics ASM330LHHX Automotive 6-Axis Inertial Module is a system-in-package (SiP) featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope optimized for automotive non-safety applications. The ASM330LHHX Inertial Measurement Unit (IMU) is suitable for telematics and dead-reckoning applications and vehicle-to-vehicle (V2X) and impact detection due to its high stability over temperature and time combined with superior performance sensing precision.

Supporting dual operating modes, the ASM330LHHX has enhanced flexibility versus application requirements, leveraging on multiple voltages and multiple ODR selections. The device also includes digital features like a finite state machine and a proprietary machine-learning core, allowing defined motion pattern detection or some complex algorithms run in the application processor to be moved to the MEMS sensor with a consistent reduction in power consumption.

The event-detection interrupts enable efficient and reliable motion-activated functions, implementing hardware recognition of free-fall events, 6D orientation, activity or inactivity, and wake-up events.

The ASM330LHHX has a full-scale acceleration range up to ±16g and a wide angular rate range of ±125dps to ±4000dps that enables its usage in a broad range of automotive applications.

The STMicroelectronics ASM330LHHX Automotive 6-Axis Inertial Module is housed in a compact 2.5mm x 3.0m x 0.83mm Grid Array (LGA) package to address ultra-compact solutions.
