The LIS2DU12 has user-selectable full scales of ±2 _g_ /±4 _g_ /±8 _g_ /±16 _g_ and is capable of measuring accelerations with output data rates from 1.6 Hz to 800 Hz. The LIS2DU12 has an integrated 128-level FIFO buffer allowing to store a wide range of data, reducing system power consumption. The embedded self-test capability allows the user to check that the sensor works in the final application. **DB4522** - **Rev 1** - **June 2021** For further information contact your local STMicroelectronics sales office. www.st.com **LIS2DU12** The LIS2DU12 has a dedicated internal engine to process motion and acceleration detection including free-fall, wake-up, single/double-tap recognition, activity/inactivity, and 6D/4D orientation. The LIS2DU12 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. **DB4522** - **Rev 1** **page 2/13** **LIS2DU12 Block diagram and pin description** ## **1 Block diagram and pin description** ## **1.1 Block diagram** **Figure 1.
