描述 Description

The IIS2DLPC is an ultra-low-power high-performance three-axis linear accelerometer with digital I2C/SPI output interface which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers.

The IIS2DLPC has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz.

The IIS2DLPC has one high-performance mode and 4 low-power modes which can be changed on the fly, providing outstanding versatility and adaptability to the requirements of the application.

The IIS2DLPC 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 IIS2DLPC 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 IIS2DLPC 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.
