Summary of IIS2ICLX 2-AXIS DIGITAL INCLINOMETER
STMicroelectronics’ IIS2ICLX is a high-accuracy, low-power two-axis linear accelerometer with digital I²C/SPI output, selectable full scale (±0.5/±1/±2/±3 g), ultra-low noise (15 µg/√Hz), strong thermal stability (<0.075 mg/°C), and embedded features (FSM, Machine Learning Core, sensor hub, FIFO, event decoding, interrupts) that enable precise inclination measurement and smart sensor-node designs.
Parts used in the IIS2ICLX Project:
- IIS2ICLX 2-axis linear accelerometer IC
- Microelectromechanical sensing element (micromachined on silicon wafer)
- CMOS interface IC circuitry (integrated with IIS2ICLX)
- I²C or SPI digital communication lines
- Power supply (to provide operating current, e.g., supporting 0.42 mA typical)
- External sensors (optional, for sensor hub integration)
STMicroelectronics’ high-accuracy and low-power two-axis linear accelerometer includes digital output.
The STMicroelectronics IIS2ICLX is a high-accuracy (ultra-low noise, high stability and repeatability) and low-power two-axis linear accelerometer with digital output.
The IIS2ICLX has a selectable full scale of ±0.5/±1/±2/±3 g and is capable of providing the measured accelerations to the application over an I²C or SPI digital interface. Its high accuracy, stability over temperature and repeatability make IIS2ICLX particularly suitable for inclination measurement applications (inclinometers).
The sensing element is manufactured using a dedicated micromachining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers. The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the characteristics of the sensing element. The IIS2ICLX has an unmatched set of embedded features (programmable FSM, Machine Learning Core, sensor hub, FIFO, event decoding, and interrupts) which are enablers for implementing smart and complex sensor nodes that deliver high accuracy and performance at very low power.
