ST25 NFC / RFID Readers

ST25 logo

Our RFID reader IC and chip portfolio covers the main frequency ranges, including 13.56 MHz ( High-Frequency) with HF NFC reader devices and 840-960 MHz ( Ultra-High Frequency) with UHF RFID reader devices.

RFID readers are devices able to setup communications and interact with a tag or a controller. There are 2 main types: fixed and portable RFID readers, which can operate at different frequency ranges depending on the target applications.

NFC/RFID Calculators to support your design

Our NFC / RFID set of calculators can help you with your ST25 NFC (13.56MHz) or RFID (UHF) designs:

  • NFC Inductance Calculator provides the inductance value of a 13.56MHz rectangular antenna based on your footprint requirements and it applies to all ST25 Tag and Reader products
  • NFC Tuning Circuit Calculator provides the component values of the matching network for a given NFC antenna and it applies to ST25R Readers
  • Link Budget calculator helps you assess whether a UHF RFID Reader can establish an RF link suitable for a reliable Reader /Tag communication and it applies to the ST25RU3993 Reader
