The ICP-20100 combines a barometric pressure and a temperature sensor that enables flexible user designs. This is supported by the availability of multiple input voltage levels including 1.2V, 1.8V and 3.3V, and a choice of I²C, I3CSM and SPI interfaces. The ICP-20100 can be configured to achieve ultra-low noise and/or ultra-low power performance.

Main features and benefits

  • Pressure operating range: 30 to 110 kPa
  • Pressure sensor temperature coefficient offset: ±0.5 Pa/ºC
  • I²C, I3C SM and SPI interface
  • FIFO, Interrupt, User-configurable ODR/OSR
  • RoHS and Green compliant

The ICP-20100 pressure sensor can operate over wide temperature ranges and deliver measurement accuracies required by a variety of applications including, 3D geolocation and emergency location service (E911), mobile indoor/outdoor navigation, sport and fitness activity tracking and altitude-hold in drones. Due to its ultra low-power consumption, the sensor extends battery life for always-on applications. With ultra-low noise pressure-sensing capabilities, the ICP-20100 can detect altitude changes of less than 5 cm.

“With its low noise architectural innovations, ICP-20100 underscores TDK’s continued commitment to bringing innovative human sensing solutions,” said Uday Mudoi, Director of Product Marketing at InvenSense, a TDK Group Company. “ICP-20100 accurately measures pressure over a long period of time, enabling new critical and important applications such as determination of accurate location of E911 calls.”

The ICP-20100 is now available in a small 2.0 mm x 2.0 mm x 0.8 mm package from TDK Corporation. A comprehensive development kit (DK-20100) and evaluation platform are also available along with necessary software to enable quick-to-market development of customer systems.
