Low-Power 2-Axis SPI/I2C Digital-Output MEMS Accelerometer
STMicroelectronics extended its range of motion sensors with a digital-output two-axis linear accelerometer. The low-power, ultra-compact LIS202DL with embedded smart features addresses a wide range of consumer and industrial applications from motion-activated user interfaces to vibration monitoring. Features of the accelerometer include click and double-click recognition, motion-detection/wake-up and high-pass filters. The configurable high-pass filters can be turned on to enable motion-activated functions and vibration monitoring regardless of whether the end product is tilted or placed upside down at the moment of measurement. The sensor also provides two separate, highly programmable interrupt signals that enable immediate notification of motion detection and click/double-click events. This gives manufacturers more freedom and flexibility in their design and applications. It is housed in a 5 × 3 × 0.9 mm LGA-14 plastic package to fit in a variety of space-constrained applications and its ultra-compact robust design provides shock survivability up to 10,000g. Built-in self-test capability allows the customer to verify the functioning of the sensor after it has been assembled on the board. The sensor is available in a dynamically selectable choice of ±2g and ±8g acceleration ranges, suited for measuring both static and dynamic acceleration.
