Three-axis MEMS accelerometer includes intelligent data processing functions
The STMicroelectronics IIS2DULPX MEMS accelerometer performs free-fall detection, self-orientation and other functions, reducing the need for external components and helping designers to reduce system complexity.
The IIS2DULPX, a three-axis linear MEMS accelerometer from STMicroelectronics, provides a range of intelligent features and data processing capabilities which enable designers to integrate multiple functions and streamline the bill-of-materials.
These features include:
- Always-on anti-aliasing filtering
- Finite state machine
- Machine learning core (MLC) with adaptive self-configuration
- Analog hub and charge variation (Qvar) sensing channel
The finite state machine and MLC produce impressive, always-on processing capabilities which operate at the edge.
The sensor has selectable full scales of ±2 g/±4 g/±8 g/±16 g, and measures acceleration in three axes at output data rates from 1.6 Hz to 800 Hz.
The IIS2DULPX has a dedicated internal engine which implements motion and acceleration detection functions, including free-fall detection, wake-up, single-, double-, triple-tap recognition, activity/inactivity detection, and 6D/4D orientation.
