Geneva, Switzerland: The STMicroelectronics iNEMO inertial module integrates three-axis sensing of linear and angular motion in a miniature 3- by 5.5- by 1-mm package (see the figure). It’s designed to provide advanced motion-sensing capabilities in today’s space-constrained consumer applications, such as smart phones, tablets, and other portable electronics.

In addition to the space-saving benefits, the iNEMO provides precise alignment of the two sensors’ reference axes and good thermal and mechanical stability. The iNEMO Engine data-fusion software employs prediction and filtering algorithms to automatically correct measurement distortions and inaccuracies.

A multi-sensor module combines a user-selectable full-scale acceleration range from 2 to 16 g with angular-rate detection from 250 to 2000 dps along the pitch, roll, and yaw axes. Addressing power constraints in battery-operated portable devices, the iNEMO includes power-down and sleep modes and two embedded FIFO memory blocks, one for each sensor, for smarter power management. In addition, it can operate with any supply voltage from 2.4 to 3.6 V.
