ST25TV series NFC tags  

Near Field Communication (NFC) Type 5 tags and labels operate in the high-frequency (HF) 13.56 MHz range and comply with the NFC-V Technology specification from the NFC Forum. The data stored in these Type 5 tags and labels is transferred to NFC smartphones or professional NFC/RFID HF readers that support the NFC Forum standardized NFC Data Exchange Format (NDEF).

ST25TV Type 5 Tag chips are certified by the NFC Forum and comply with the industrial ISO/IEC 15693 RFID specifications thus providing consistency of behavior across NFC implementations. They set the foundation for interoperability with NFC smartphones and NFC/RFID HF readers.

STMicroelectronics’ ST25TV Type 5 NFC tag ICs combine the convenience of the ISO 15693 vicinity standard[1] with the extra advantage of tamper detection as well as strong cloning-prevention, data-protection, and user-privacy features. ISO 15693 tags can benefit from smaller antennas and more reliable data exchange over longer distances than ISO 14443 tags. As the only ISO 15693 IC with tamper detection, the ST25TV makes tags for applications like tamper-proof packaging and electronic article surveillance safer, smaller, easier to install, and easier to read. Capable of interacting with smartphones or RFID readers, it is equally suited to consumer or professional use. ST’s new certified NFC-Forum chip is suitable for cloud-management based brand protection, product authentication, and anti-counterfeiting applications using NFC smartphones in sectors such as luxury goods, pharmaceuticals, and other high-value products. Other features in addition to tamper detection protect contactless use cases throughout retail, smart industry, logistics, and digital living, including physical-web applications like smart posters, asset tracking, access control, identity authentication, and gaming. Each ST25TV IC has an individual 64-bit device identifier and comes digitally signed using ST’s TruST25™ methodology to prove origin and prevent cloning. User memory is read/write password protected with up to 64-bits encryption and block-level write locks. There are also Kill and Untraceable modes with passwords and data/configuration locks to protect consumer privacy. ST25TV ICs support all ISO/IEC 15693 modulations, coding, subcarrier modes and data rates, and allow versatile block read/write modes with fast-read access at up to 53 Kbit/s. Two EEPROM density options are available. The 512-bit ST25TV512 and 2-Kbit ST25TV02K allow configurable memory portioning, provide minimum endurance of 100,000 write cycles, and ensure 60-year data retention for durability and long-lasting protection. The ST25TV512 and ST25TV02K are available as 75-micron or 120-micron sawn and bumped wafer, or in 1.7mm x 1.4mm 5-lead UFDFPN5, priced from $0.10 for orders of 1000 pieces. Selected configurations are in volume production, and the full range of package and memory options will be available by mid-2018.

ST25TV Type 5 NFC Tag ICs are the first solution to combine the convenience of the longer read range of the ISO/IEC 15693 vicinity standard with a tamper detect capability. When compared to other NFC types, ST25TV tags are easier to tap and read by consumers, therefore improving the user experience designed by each brand. Brands and manufacturers now have access to smaller NFC tag labels and stickers, which are safer and easier to install for enhanced engagement with their customers. This unique solution can be used throughout the product lifecycle, from the point of manufacture up to consumer engagement at the point of sales and beyond. It gives a digital life to everyday consumer goods.

ST25TV tags can be used for cloud management-based brand protection associated with tamper detection in different application sectors such as wine & spirits, pharmaceuticals and luxury items. They can also be used for product identification as well as logistics and traceability applications with a long-range HF RFID reader infrastructure.
