STMicroelectronics IIS2DLPC 3-axis MEMS accelerometer

Click2Contact

The STMicroelectronics IIS2DLPC 3-axis MEMS accelerometer can change operating mode on the fly, from ultralow power to high resolution. The sensor can provide continuous contextual awareness to wake the host system when action is required and take its measurements before returning to ultralow-power operation.

With this extra flexibility, users can build long-lasting battery-powered industrial sensor nodes or medical devices, tamperproof 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 optimise power consumption in wide-ranging application scenarios. Low noise, down to 90 μg/√Hz in high-resolution mode, permits proper measurement. Additional features 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 product is specified over an extended temperature range from -40 to +85°C.
