With the ST25 product family, ST offers a complete portfolio of NFC and RFID tag and reader ICs for a wide variety of NFC-enabled solutions. Currently found in contactless payment, access control and public transport ticketing systems, NFC technology is a convenient, always-on low power short-range wireless link that is driving the growth for convenient pairing, diagnostic readout, data tracking, and parameter setting use cases in Consumer, Industrial, Automotive and Medical applications. The benefit of our 10 years longevity program is available for Industrial-grade and Medical NFC / RFID applications.

Operating in the 13.56MHz RFID HF band, ST25 NFC tags and dynamic tags comply with ISO14443 type A and B, ISO15693 and NFC Forum standards and offer a range of EEPROM memory sizes from 512-bit to 64-Kbit.

ST25TAST25TV tags and ST25DV dynamic tags are NFC Forum certified. The certification provides consistency of behavior across NFC implementations and sets the foundation for interoperability.

ST25R HF readers are compliant with ISO14443 type A and B, ISO15693, ISO18092, FeliCa and NFC Forum standards. They are supporting very high bit rate (VHBR) technology and up to 1.4 W output power.

ST25RU UHF readers are compliant with ISO18000 and ISO29143 standards.

ST offers a comprehensive range of tools to evaluate and develop NFC/RFID solutions: NFC Discovery starter kits, NFC STM32 Nucleo MCU expansion boards, ST25 reference software and antenna design tool in order to ease the design process and cost.
