STMicroelectronics – LIS2DS12: Ultra-Low Power High-Performance 3-Axis Accelerometer
The LIS2DS12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “pico” family which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers.
The embedded self-test capability allows the user to check the functioning of the sensor in the final application.
The LIS2DS12 has a dedicated internal engine architecture in order to process internally motion and acceleration detection including free-fall, wakeup, single and double-tap detection, activity-inactivity, portrait and landscape detection, step counter and step detection along with significant motion detection.
The LIS2DS12 is available in a small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
