MEMS Accelerometer Ready For Industrious Employment

STMicroelectronics’ IIS2DLPC three-axis MEMS accelerometer can change operating mode on the fly, from ultra-low power to high resolution, enabling high-accuracy measurements within a limited energy budget. The sensor can provide continuous contextual awareness to wake the host system when action is required and take highly accurate measurements before returning to ultra-low power operation.


A choice of four reduced-power modes lets users optimize power consumption in wide-ranging application scenarios. A noise figure down to 90 μg/√Hz in high-resolution mode accounts for impressive measurement accuracy. Additional features include easy-to-use one-shot data conversion and a 32-level FIFO for storing batched data to reduce CPU intervention. An integrated temperature sensor and built-in self-test capability are also provided.
