STMicroelectronics ST25TV02KC RFID Transponder
STMicroelectronics ST25TV02KC RFID Transponder is an NFC/RFID tag IC that includes ST's state-of-the-art patented technology. The RFID Transponder provides an Augmented NDEF option, a tamper detection interface, and specific modes to protect customer privacy. The Augmented NDEF feature is a contextual automatic NDEF message service that allows the tag to respond with dynamic content without an explicit update of the EEPROM by the end-user. The tamper detection interface is only available on ST25TV02KC-T. This interface is not offered on the ST25TV02KC‑A device.
The STM ST25TV02KC RFID Transponder holds a digital signature generated by TruST25 (a set of software and procedures) to prove the origin of the chip in cloning detection. This digital signature also 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 contactless interface complies with the ISO/IEC 15693 standard and NFC Forum Type 5 tag specification.
