LIS3DSH MEMS digital output motion sensor: ultra-low-power high-performance three-axisnan accelerometer Datasheet - production data Description The LIS3DSH is an ultra-low-power high- performance three-axis linear accelerometer belonging to the nano family with an embedded state machine that can be programmed to implement autonomous applications. /* The LIS3DSH has dynamically selectable full scales of 2g/4g/6g/8g/16g and is capable of measuring accelerations with output data rates Features from 3.125 Hz to 1.6 kHz. Wide supply voltage, 1.71 V to 3.6 V The self-test capability allows the user to check the functioning of the sensor in the final Independent IOs supply (1.8 V) and supply application. voltage compatible The device can be configured to generate Ultra-low power consumption interrupt signals activated by user-defined motion 2g/4g/6g/8g/16g dynamically selectable patterns. full scale 2 The LIS3DSH has an integrated first-in, first-out I C/SPI digital output interface (FIFO) buffer allowing the user to store data in 16-bit data output order to limit intervention by the host processor. Programmable embedded state machines The LIS3DSH is available in a small thin plastic Embedded temperature sensor land grid array package (LGA) and is guaranteed to operate over an extended temperature range Embedded self-test from -40 C to +85 C. Embedded FIFO 10000 g high shock survivability Table 1.
