IIS2DLPC MEMS digital output motion sensor: high-performance ultra-low-power 3-axis accelerometer for industrial applications Datasheet - production data Description The IIS2DLPC is an ultra-low-power high-performance three-axis linear accelerometer with digital IC/SPI output interface which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers. Features The IIS2DLPC has user-selectable full scales of 2g/4g/8g/16g and is capable of measuring 2g/4g/8g/16g full scale accelerations with output data rates from 1.6 Hz to Multiple operating modes reconfigurable on the fly: 1600 Hz. from ultra-low-power to high-performance high- The IIS2DLPC has one high-performance mode and 4 resolution mode low-power modes which can be changed on the fly, providing outstanding versatility and adaptability to the Ultra-low power consumption: 50 nA in power-down requirements of the application. mode, below 1 A in active low-power mode, 120 A in high-performance mode The IIS2DLPC has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in order to Output data rates from 1.6 Hz to 1600 Hz bandwidth limit intervention by the host processor. up to 800 Hz The embedded self-test capability allows the user to Single data conversion on demand check the functioning of the sensor in the final Very low noise: down to 90 g/Hz application. The IIS2DLPC has a dedicated internal engine to 32-level FIFO and 2 independent programmable process motion and acceleration detection including interrupts free-fall, wakeup, highly configurable single/double-tap High-speed IC/SPI digital output interface recognition, activity/inactivity, stationary/motion Supply voltage, 1.62 V to 3.6 V detection, portrait/landscape detection and 6D/4D Embedded temperature sensor orientation. The IIS2DLPC is available in a small thin plastic land Self-test grid array package (LGA) and it is guaranteed to operate 10000 g high shock survivability over an extended temperature range from -40 C to ECOPACK, RoHS and Green compliant +85 C.
