ST Introduces 3-axis Gyroscope for Automotive Apps
Aims to add positioning accuracy and stability to a wide range of automotive applications
Feb 20, 2012
STMicroelectronics has unveiled the market’s first 3-axis digital-output gyroscope that meets the industry-standard qualification for automotive integrated circuits (AEC-Q100). ST’s newest angular-rate sensor aims to add positioning accuracy and stability to a wide range of automotive applications, including in-dash navigation, telematics and vehicle tolling systems.
ST’s A3G4250D gyroscope measures angular rates up to +/-250dps (degree per second). An on-chip IC interface converts the angular-motion data into a 16-bit digital bit stream that is transmitted with high reliability to a dedicated microcontroller chip through a standard SPI or IC protocol. The device provides two output lines (interrupt and data ready) and four user-selectable output data rates.
ST’s 3-axis gyroscope for automotive applications has been designed and produced using the same manufacturing-process technology that ST has already successfully applied to 1.8 billion motion sensors sold in the market. ST customers benefit from the industry-unique combination of state-of-the-art product design and ST’s capability to manage the whole supply chain, leveraging large-scale production capacity at the Company’s dedicated 8-inch MEMS production lines.
