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.
Suited to industrial applications, the IIS2DLPC is specified over an extended temperature range from -40°C to +85°C. In production now, it’s packaged as a 2 mm x 2 mm x 0.7 mm plastic land grid array (LGA) device, priced from $1.10 each/1,000. For greater enlightenment, peruse the IIS2DLPC datasheet.
