Accelerometer AIS328DQ for automotive-grade 3-axis small g value

STMicroelectronics, the world's leading supplier of MEMS (Micro Electro Mechanical Systems), further expands its sensor product portfolio, launching new automotive-grade 3-axis accelerometers with small g values. Combining the advantages of low power consumption, small size, high precision, and robust performance, ST's new accelerometer locks a variety of automotive applications, including vehicle tracking, event recording, equipment abnormal use monitoring, and navigation for assisted navigation functions. Bit estimation.

ST's AIS328DQ can detect acceleration motions in three axes, convert motion and tilt information into high-resolution digital signals, and transmit them to the microcontroller through a standard SPI or I2C interface. Within an optional full-scale range of ± 2g / ± 4g / ± 8g, the accelerometer can provide very accurate data output, and can maintain excellent stability for a long time operation within the operating temperature range.

ST's AIS328DQ has excellent anti-collision and anti-electromagnetic interference functions, and meets the strict automotive integrated circuit stress test standard AEC-Q100 set by the Automotive Electronics Association (AEC).

Due to the wide operating temperature range of -40 ° C to 105 ° C, the AIS328DQ sensor can be installed in the cabin or in a heating module (such as a power circuit). The self-detection program built into the sensor can be started at any time to verify the normal function of the accelerometer.

This latest automotive-grade accelerometer AIS328DQ uses the same process as STMicroelectronics has sold more than 850 million motion sensors.

ST's AIS328DQ automotive accelerometer has begun to provide samples, and the product is expected to be officially mass produced in the third quarter of 2011.
