December 2016 DocID17530 Rev 21/54 LIS3 DHMEMS digital output motion sensor : ultra -low-power high-performance 3-axis "nano" accelerometerDatasheet - production dataFeatures Wide supply voltage, V to V Independent IO supply ( V) and supply voltage compatible ultra -low-power mode consumption down to 2 A 2g/ 4g/ 8g/ 16g dynamically selectable full scale I2C/SPI digital output interface 16-bit data output 2 independent programmable interrupt generators for free-fall and motion detection 6D/4D orientation detection Free-fall detection motion detection Embedded temperature sensor Embedded self-test Embedded 32 levels of 16-bit data output FIFO 10000 g high shock survivability ECOPACK.

2 RoHS and Green compliant Applications motion activated functions Free-fall detection Click/double-click recognition Intelligent power saving for handheld devices Pedometers Display orientation Gaming and virtual reality input devices Impact recognition and logging Vibration monitoring and compensationDescriptionThe LIS3DH is an ultra -low-power high-performance three-axis linear accelerometer belonging to the nano family, with digital I2C/SPI serial interface standard output . The device features ultra -low-power operational modes that allow advanced power saving and smart embedded functions.

3 The LIS3DH has dynamically user-selectable full scales of 2g/ 4g/ 8g/ 16g and is capable of measuring accelerations with output data rates from 1 Hz to kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. The device may be configured to generate interrupt signals using two independent inertial wake-up/free-fall events as well as by the position of the device itself. Thresholds and timing of interrupt generators are programmable by the end user on the fly. The LIS3DH 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.

4 The LIS3DH is available in small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 C to +85 C. /*$ [ [ PP Table 1.
