LIS2DS12 MEMS digital output motion sensor: ultra-low-power, high-performance 3-axispic accelerometer Datasheet - production data Description The LIS2DS12 is an ultra-low-power, high- performance three-axis linear accelerometer belonging to the pico family which leverages on the robust and mature manufacturing processes /* PP already used for the production of micromachined accelerometers. Features The LIS2DS12 has user-selectable full scales of 2g/4g/8g/16g and is capable of measuring Supply voltage, 1.62 V to 1.98 V accelerations with output data rates from 1 Hz to Independent IOs supply (1.8 V) and supply 6400 Hz. voltage compatible The LIS2DS12 has an integrated 256-level first- Ultra-low power consumption in, first-out (FIFO) buffer allowing the user to store 2g/4g/8g/16g full scale data in order to limit intervention by the host 2 processor. High-speed I C/SPI digital output interface Low noise The embedded self-test capability allows the user to check the functioning of the sensor in the final 16-bit data output application. Embedded temperature sensor The LIS2DS12 has a dedicated internal engine Self-test architecture in order to process internally motion 256-level FIFO and acceleration detection including free-fall, wakeup, single and double-tap detection, activity- 10000 g high shock survivability inactivity, portrait and landscape detection, step ECOPACK , RoHS and Green compliant counter and step detection along with significant motion detection. Applications The LIS2DS12 is available in a small thin plastic Motion-activated functions and user interfaces land grid array package (LGA) and it is guaranteed to operate over an extended Gesture recognition and gaming temperature range from -40 C to +85 C.
