NFC Type 5 / RFID tag IC with 2-Kbit EEPROM, product identification and protection
ST25TV02K and ST25TV512 are NFC/RFID tag ICs with a tamper-proof feature, and specific modes to protect tag access, such as Untraceable mode.
These devices feature a digital signature used to prove the origin of the chip in cloning detection, embed a configurable EEPROM with 60-year data retention, and can be operated from a 13.56 MHz long-range RFID reader or an NFC phone.
The contactless interface is compatible with the ISO/IEC 15693 standard and NFC Forum Type 5 tag.
