Description:

The MIS2DU12 is a linear 3-axis accelerometer with advanced digital functions whose MEMS and ASIC have been expressly designed to build an outstanding ultralow-power architecture in which the antialiasing filter operates with a power consumption among the lowest in the market.The device 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 800 Hz.The MIS2DU12 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.The device 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 MIS2DU12 is available in a small 2.0 x 2.0 mm plastic, land grid array (LGA) package only 0.74 mm thin, which places it among the smallest solution available in the market. It is guaranteed to operate over an extended temperature range from -40°C to + 85°C.
