– STMicroelectronics ( www.st.com , Country Manager for Korea Sung-keun Kang), a leader in the MEMS field, has launched a new automotive-grade 3-axis low-g accelerometer. Combining low power consumption, a small footprint, high precision, and rugged performance, ST’s new accelerometer can be used in a variety of automotive applications such as vehicle tracking, event logging, abuse monitoring, and dead-reckoning for enhanced navigation performance.

The new AIS328DQ detects acceleration along three axes and converts motion and tilt information into high-resolution digital signals, transmitting them to a microcontroller via a standard SPI or I2C interface. This accelerometer provides highly accurate output over a user-selectable full-scale range of ±2g/±4g/±8g and boasts excellent stability over time and temperature.

ST’s AIS328DQ, which offers excellent resistance to shock and electromagnetic interference, has obtained AEC-Q100 certification, a critical stress test for automotive ICs defined by the AEC (Automotive Electronics Council).

This sensor, capable of operating over an extended temperature range of -40°C to 105°C, is placed inside a cabin or module containing a self-heating element, such as a power section.
