TDK InvenSense SmartPressure™ Barometric Pressure Sensor

TDK InvenSense SmartPressure™ Barometric Pressure Sensor is a high-accuracy, low power, barometric pressure, and temperature sensor solution. This ICP-20100 module integrates a capacitive pressure sensor for monitoring pressure changes in the range of 30kPa to 110kPa. The sensor also has a DSP module for on-chip calibration with an analog-to-digital converter (ADC), digital filtering, a FIFO, and has I2C, I3CSM, and SPI interfaces available. The ICP-20100 can be configured to achieve ultra-low noise or ultra-low power performance and is flexible to perform anywhere in-between. TDK InvenSense SmartPressure Barometric Pressure Sensor is available in a closed 2mm x 2mm x 0.8mm 10-pin LGA package with a vent hole. Applications include smartphones and tablets, wearable Sensors, drones and toys, fitness trackers, home and building automation, and weather stations.


  • Digital-output pressure and temperature sensors, with programmable output – all pressure, all temperature, or pressure and temperature
  • Programmable noise performance down to 0.5Parms through programmable oversampling ratio (OSR)
  • 96-byte FIFO buffer enables the application processor to read up to 16 pressure-temperature pairs in a burst
  • Digital filtering for pressure signals
    • Finite impulse response (FIR) filter for improved noise performance
    • Infinite impulse response (IIR) filter for filtering of pressure glitches
  • User-programmable interrupt
  • RoHS and Green compliant
