Certified NFC Type 5 chips bring tamper-detect capability to smaller tags

STMicroelectronics’ ST25TV Type 5 NFC tag ICs combine the convenience of the ISO 15693 vicinity standard ISO 15693 tags, operate at the 13.56 MHz frequency and offer maximum read distance of 1 to1.5 metres 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 such as tamper-proof packaging and electronic article surveillance safer, smaller, easier to install, and easier to read, says the company. Capable of interacting with smartphones or RFID readers, this IC 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 such as 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(tm) 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.
