AI-Enhanced Smart Accelerometer

STMicroelectronics has launched three new smart accelerometers with advanced processing engines built-in to extend sensor autonomy, enabling systems to respond more quickly to external events while lowering power consumption.

The LIS2DUX12 and LIS2DUXS12 leverage ST’s third-generation MEMS technology, adding programmable capabilities including machine-learning core (MLC), advanced finite state machine (FSM), and an enhanced pedometer. A third entry-level accelerometer, LIS2DU12, is also available for less demanding applications. All three products are equipped with the latest industry standard I3C interface. The three devices integrate the common digital features for detecting events, as well as an anti-aliasing filter for high accuracy at lower sampling frequencies with performance benefits for accurate gesture detection at negligible power consumption.

The LIS2DUXS12 is also capable of sensing change in electrostatic environment, which can be used for presence and proximity detection. This unique feature is called Qvar.

The LIS2DUX12 and LIS2DUXS12 are in production now and available in a 2mm x 2mm x 0.74mm 12-lead LGA package. Pricing is from $1.38 for the LIS2DUX12 and $1.43 for the LIS2DUXS12, for orders of 1000 pieces. The LIS2DU12, in the same package type, is available for $1.20.
