LIS2DTW12TR MEMS Digital Output Dual Motion and Te

STMicroelectronics' LIS2DTW12 is an ultra-low-power high-performance three-axis linear accelerometer and temperature sensor belonging to the "femto" family which leverages on the robust and mature manufacturing processes already used to produce micromachined accelerometers. The device 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 1600 Hz.

The LIS2DTW12 has an embedded 0.8°C (typical accuracy) temperature sensor with ODRs ranging from 50 Hz to 1.6 Hz and resolution from 8 bits to 12 bits. The LIS2DTW12 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. The embedded self-test capability allows the user to check the functioning of the sensor in the final application.

The device has a dedicated internal engine to process motion and acceleration detection including free-fall, wakeup, highly configurable single/double-tap recognition, activity/inactivity, stationary/motion detection, portrait/landscape detection, and 6D/4D orientation.

The LIS2DTW12 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.
