STMicroelectronics ST25TV02KC/ST25TV512C RFID Transponders

STMicroelectronics ST25TV02KC/ST25TV512C RFID Transponders are NFC/RFID tag ICs that include ST’s state-of-the-art patented technology. The RFID Transponders provide 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 and ST25TV512C devices.

The STM ST25TV02KC and ST25TV512C RFID Transponders hold 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.
