Operating in the 13.56 MHz (RFID) HF band, ST25 NFC tags and dynamic tags comply with ISO/IEC 14443 type A and B,  ISO/IEC 15693 and NFC Forum standards and offer a range of EEPROM memory sizes from 512-bit to 64-Kbit.

ST25TA, ST25TV tags and ST25DV dynamic tags are NFC Forum certified. The certification provides consistency of behavior across NFC implementations and sets the foundation for interoperability.

ST25 NFC reader ICs also run in the 840-960 MHz UHF band and are compliant with ISO/IEC 18092, ISO/IEC 18000, ISO/IEC 29143, FeliCa, NFC Forum, EMVCo and PBOC standards with very high bit rate (VHBR) technology and up to 1.4 W output power..

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.
