ST25 NFC / RFID Readers

STMicroelectronics

The ST25R HF reader series provides multiprotocol support for 13.56 MHz NFC / RFID communications as ISO / IEC 14443 Type A or B, ISO / IEC 15693, ISO / IEC 18092, FeliCa and NFC Forum protocols.

They integrate an SPI interface for interface to a host microcontroller.

  • The 95HF products are suitable for a wide spectrum of applications including identification, authentication, product configuration, access control, door locks and industrial tag readers.
  • ST25R39xx devices provide a complete solution for payment and point of sale terminals (POS) with the ST25R3911B/12/13 boasting EMVCo & PBOC certifications while the ST25R3914/15 are full AEC-Q100 grade 1 automotive grade making them ideal for keyless entry and immobilizer applications. They are also ideal applications like access control, door locks and gaming.

 

The ST25RU UHF reader series provides multiprotocol support for the 840-960 MHz UHF band compliant with ISO 18000 6c & b, ISO 29143 and UHF EPC GEN2 RAIN standards.

  • The ST25RU39xx devices are optimized for solutions for supply chain and logistics applications, asset tracking, cold chain management and a variety of IoT based applications.
