The automotive-grade six-axis inertial sensor ASM330LHH from STMicroelectronics, a world-leading semiconductor supplier spanning multiple electronic applications, provides ultra-high-resolution motion tracking for advanced in-vehicle navigation and information service systems.

The ASM330LHH can meet the continuity and accuracy requirements of automated services for vehicle positioning. When the satellite signal is blocked, the ASM330LHH can provide sensor data for advanced dead reckoning algorithms to calculate the precise position of the car. Blocked satellite signals often occur in high-rise city streets, tunnels, covered roads, garages or dense forests. The ASM330LHH‘s advanced low-noise, temperature-stable design enables reliable telematics services such as road and bridge electronic toll collection, remote diagnosis and electronic rescue. Sophisticated six-axis inertial sensing data also meets the needs of advanced autonomous driving systems.

Magneti Marelli has selected the ASM330LHH for its advanced telematics system, which will also become the original standard for future models of global automakers.

Like ST‘s other MEMS sensors, ST controls the entire manufacturing process of the ASM330LHH. End-to-end control, from sensor design to wafer fabrication, packaging and testing, calibration and supply, enables ST to develop high-performance sensors, and provides customers with a robust and responsive supply chain with rigorous online screening Quality Control Plan.

Andrea Onetti, Vice President of Analog, MEMS and Sensor Products at STMicroelectronics, said: "ST is the number one MEMS sensor manufacturer in the automotive non-safety market such as in-vehicle navigation and information service systems. Our latest generation of inertial sensors - automotive-grade The ASM330LHH enables precise positioning, making car driving safer and smarter.”

ASM330LHH Details

1. The operating temperature range is up to 105°C, so that the electronic controller is no longer limited by the installation location, and designers can install it in high temperature locations, such as in the roof smart antenna or near the engine compartment.

2. Ultra-low noise enables higher measurement resolution by minimizing integration errors when positioning is solely dependent on the sensor.

3. High linearity and built-in temperature compensation mechanism, no need to add any external compensation algorithm within the working range.

4. The lowest power consumption of similar products, when battery life is critical, power management efficiency can be optimized.

5. Passed the AEC-Q100 automotive-grade robustness standard certification.

6. Based on the proven STMicroelectronics unique ThELMA[2] MEMS process, a 3-axis accelerometer and a 3-axis angular rate sensor (gyroscope) can be integrated on the same wafer, and the chip yield, quality and reliability are all optimal level.

7. The electronic interface uses ST‘s 130nm HCMOS9A technology to integrate the signal chain shared by the two sensors on the same die.

8. The development kit includes reference designs, as well as STMicroelectronics‘ Teseo™ satellite positioning module and associated software. The dead reckoning algorithm attached to the TeseoIII GNSS receiver chipset already supports the ASM330LHH to generate high accuracy output suitable for autonomous navigation.

9. The slim and compact size of 3mm x 2.5mm x 0.83mm will not substantially affect the size of any onboard module.

10. Available in a Contact Array (LGA) package.

Summary: The above is the introduction of high-precision MEMS sensors from STMicroelectronics, hoping to help everyone understand.
