STMicroelectronics ST25TV RFID Tag IC with EEPROM

STMicroelectronics ST25TV RFID Tag IC with EEPROM is an NFC/RFID tag IC with a tamper-proof feature and specific modes to protect customer privacy. The device features a digital signature generated by TruST25™ (a set of software and procedures), used to prove the origin of the chip in cloning detection. The ST25TV embeds a configurable EEPROM with 60-year data retention and can be operated from a 13.56MHz long range RFID reader or an NFC phone. The STMicroelectronics ST25TV RFID Tag IC with EEPROM contactless interface is compatible with the ISO/IEC 15693 standard and NFC Forum Type 5 tag.
