3-acis accelerometer changes modes on the fly

Edith 2018-11-07

ST’s IIS2DLPC 3-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 measurements before returning to ultra-low power operation.


With this extra flexibility, users can build longer-lasting battery-powered industrial sensor nodes or medical devices, tamper-proof smart meters, and smart power-saving or motion-activated functions.


In addition, the opportunity for  low power consumption enables smart accessories for industrial machinery or robotics to be created as convenient battery-powered add-on modules that require minimal integration effort.


A choice of four reduced-power modes lets users optimize power consumption in wide-ranging application scenarios.


Very low noise, down to 90μg/√Hz in high-resolution mode, permits outstanding measurement accuracy.


Additional features of the IIS2DLPC give users extra control over power consumption, including 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.


Especially suited to industrial applications, the IIS2DLPC is specified over an extended temperature range from -40°C to +85°C and covered by ST’s 10-year product-longevity scheme ensuring long-term availability.


The IIS2DLPC is in production now, packaged as a 2mm x 2mm x 0.7mm plastic land grid array (LGA) device, priced from $1.10 for orders of 1000 pieces.
