ASM330LHHX – Artificial intelligence applied in automotive sensors


Automotive 6-axis inertial module with embedded machine learning core and dual operating modes

A system-in-package featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope, the ASM330LHHX has an extended temperature range up to +105 °C designed to address automotive non-safety applications.

The ASM330LHHX provides an incredible level of customization thanks to its capability to support up to 16 embedded finite state machines that can be programmed and run independently for motion detection such as vehicle status (stationary or moving), anti-theft alarm, and shock detection.

steval mki212v1

An effective solution for fast system prototyping and device evaluation directly within your own application, the STEVAL-MKI212V1 provides the complete ASM330LHHX pinout and comes ready-to-use with the required decoupling capacitors on the VDD power supply line.

The adapter is supported by the STEVAL-MKI109V3 motherboard, which includes a high-performance 32-bit microcontroller functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable graphical user interface (Unico-GUI), or dedicated software routines for customized applications.

mlc examples

Available in ST's public GitHub repository, you will find information, examples and configurations for the Machine Learning Core (MLC), a hardware processing engine dedicated to the most extreme real-time edge computing. The advantage is that it reduces power consumption by moving the processing of certain Machine Learning algorithms from the application processor to the ST sensor.
