STMicroelectronics ST25TV512 Type 5 NFC tag IC tag chip integrates the convenience and tamper detection of the ISO 15693 proximity card standard with robust cloning protection, data protection and user privacy. The advantages of ISO 15693 tags over ISO 14443 tags include smaller antennas, longer communication distances and more reliable data exchange. As the only ISO 15693 IC with tamper detection, the ST25TV512 makes tags used for tamper-resistant packaging, electronic article monitoring and other functions more secure, smaller, simpler to install and easier to read, and capable of interacting with smartphones or RFID readers. The chip is equally suitable for consumer electronics or professional products. STMicroelectronics new NFC-Forum authentication chip works with NFC-enabled smartphones to provide cloud-based management of brand protection, product authentication and fidelity anti-counterfeiting for high-value product markets such as luxury goods and pharmaceuticals. In addition to tamper detection, other features protect contactless use cases in retail, smart industry, logistics and digital lifestyles, including smart posters, asset tracking, የመዳረሻ መቆጣጠሪያ, authentication and physical Web applications such as gaming. Each ST25TV512 IC has an individual 64-bit device identifier and is digitally signed using STMicroelectronics TruST25TMmethod to prove origin and prevent pirate cloning. User memory read/write operations are password-protected with up to 64-bit encryption algorithms and block-level write-lock protection. Tag-off (ለመግደል) mode and untraceable mode utilize password locks and data/configuration locks to protect consumer privacy. The ST25TV512 IC supports all ISO/IEC 15693 ድምፅን, ኮድ መስጠት, subcarrier modes and data rates, and supports block read/write modes at different rates, including fast read access at up to 53 Kbit / ዎች. The 512-bit EEPROM allows for configurable memory partitioning, with an erasure resistance of no fewer than 100,000 cycles and data retention of up to 60 ዓመታት. Suitable for long-term permanent data protection applications. Choose ST25TV series NFC as the access card and enable the data area encryption function, the access card will not be copied.
