MEMS accelerometer addresses broad range of automotive applications
October 29, 2010 // Christoph Hammerschmidt
STMicroelectronics has expanded its sensor portfolio with an automotive-grade three-axis low-g accelerometer. Combining low power consumption and small footprint with high precision and robust performance, the device targets a wide range of automotive applications, including vehicle tracking, event recording, abuse monitoring, and dead-reckoning for enhanced navigation capabilities.
The AIS328DQ senses acceleration along all three axes and converts the motion and tilt information into a high-resolution digital signal that it transmits to a microcontroller through a standard SPI or I2C interface. According to the vendor, the accelerometer provides very accurate output across user-selectable full-scale ranges of up to ±8g. In addition, the sensor is boasting excellent stability over time and temperature, ST promises.
The AIS328DQ is qualified to AEC-Q100, a critical stress-test qualification for automotive integrated circuits established by the Automotive Electronics Council (AEC). With an extended temperature range from -40 to 105°C, the sensor can be used inside the cabin or inside modules that have self-heating components, like power stages. An embedded routine can be activated at any time to verify correct functioning of the device.
Samples of the AIS328DQ automotive accelerometer are available and volume production is scheduled for Q3 2011. Unit pricing is below $3 for volumes in the range of 100,000 pieces.
