The LIS2DW12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers.The LIS2DW12 has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz. The LIS2DW12 has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor.
