ST’s smallest MEMS modules packs 6 degrees of freedom in 16 mm3

The LSM330D iNEMO multi-sensor module from STMicroelectronics is a new inertial module that integrates three-axis sensing of linear and angular motion in a miniature 3 x 5.5 x 1mm package. Reducing size by almost 20% over devices currently in production, ST’s newest iNEMO module has six degrees of freedom and delivers advanced motion-sensing capabilities for space-constrained consumer applications such as smart phones, tablets and other portable electronic devices.

In addition to the space-saving benefits, the LSM330D enhances user experience and motion-sensing realism through its advanced design and real-time sensor data fusion capabilities.  The module design ensures precise alignment of the two sensors’ reference axes and superior thermal and mechanical stability, while ST’s iNEMO Engine data-fusion software employs sophisticated prediction and filtering algorithms to automatically correct measurement distortions and inaccuracies.

The new multi-sensor module combines a user-selectable full-scale acceleration range from 2 to 16g 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 module includes power-down and sleep modes and two embedded FIFO (first-in first-out) memory blocks, one for each sensor, for smarter power management. In addition, it can operate with any supply voltage over the range of 2.4 to 3.6V.

Fully software-compatible with ST’s latest-generation 3-axis digital accelerometers (LIS3DH) and gyroscopes (L3GD20), the new iNEMO module makes it easy for customers using ST’s single-function sensors to upgrade their designs, reducing the board size, number of external components, and overall application system complexity.

The smallest 6 DoF (degrees of freedom) device in ST’s iNEMO inertial module family, the LSM330D is available in engineering samples. Unit pricing is $2.75 for volumes in the range of 1,000 pieces. If your company has a high-volume need, please contact your ST sales office.
