LSM6DSV16X 6-axis Inertial Measurement Unit

STMicroelectronics has introduced the new flagship 6-axis inertial measurement unit (IMU) LSM6DSV16X that features ST’s Sensor Fusion Low Power (SFLP) technology, Artificial Intelligence (AI), and adaptive-self-configuration (ASC) for superior power optimization. It enables sophisticated processing in the edge, making the device ideal for advanced 3D phone mapping, context awareness in laptops and tablets, reliable and precise gesture recognition for XR headsets, and always-on activity tracking.

The IC integrates an enhanced finite state machine (FSM), to detect fast events and custom gestures. With ASC, the sensor can optimize its own settings such as measurement range and operating frequency, independently and on the fly, without host intervention. Teamed with ST’s Sensor Fusion Low Power (SFLP) technology, it enables the IMU to host fast and powerful edge processing with minimal energy demand. SFLP allows gesture recognition or continuous tracking while drawing as little as 15µA.

As a high-accuracy 6-axis MEMS IMU, the LSM6DSV16X contains a 3-axis low noise accelerometer and 3-axis gyroscope for accurate sensing in an industry-standard size and with the new I3C interface. Both structures benefit from high stability after reflow soldering, which saves equipment manufacturers recalibrating the IMU on the production line and guarantees sensing performance.

Key Features

  • 3-axis digital accelerometer and a 3-axis digital gyroscope 

  • Finite State Machine (FSM) to quickly detect events

  • Machine Learning Core (MLC) for accurate and reliable AI algorithms

  • Automatic System Configuration (ASC) for device self-configuration

  • Sensor Fusion Low Power (SFLP) for always-on spatial orientation

  • Configurable pedometer to accurately track footsteps

  • Qvar®, electrical potential sensing channel for advanced UIs

The LSM6DSV16X is in production now in a 2.5mm x 3.0mm x 0.83mm 14-lead LGA package, priced from $2.98 for orders of 1000 pieces.
