STMicroelectronics LIS2DU12

LIS2DU12TR is an ultralow-power accelerometer with anti-aliasing and motion detection. This 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 anti-aliasing filter operates with a current consumption among the lowest in the market. It 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. It is used in applications such as wearable devices (wristband and smart watches), game controllers, hearing aids and portable healthcare devices, true wireless stereo, wireless sensor nodes, motion-activated user interfaces (screen rotation, tap, double tap), and asset trackers.
