The ST25R HF RFID / NFC reader series provides multiprotocol support for 13.56 MHz NFC / RFID communications such as ISO 14443 Type A or B, ISO 15693, ISO 18092, FeliCa and NFC Forum protocols. Our NFC reader ICs and chips integrate an SPI interface to communicate with a host microcontroller.

The ST25RU Rain / UHF RFID reader IC provides energy efficient hardware support for communication protocols such as ISO 18000-62/63, EPC Gen2 v 2.1, ISO 29143. Other UHF RFID protocols may be implemented in the IC's transparent mode. The Reader IC allows a tag read speed of up to 500 [tags/sec] for high tag update rates. Large tag populations can be inventoried with a competitive tag detection rate provides by the IC's high receive sensitivity and the efficient tag anti-collision algorithm implemented in the open reader firmware.

As a main provider of Near-Field Communication technology, ST's complete NFC reader portfolio will help you design and develop the most effective and secure contactless solutions for all embedded, payment and automotive applications.
