ST25TV NFC tags with Augmented NDEF & Tamper Detection

STMicroelectronics Powers Creative NFC Applications with Dynamic Message Content & Anti-Tamper in New Type-5 Tags

Uniquely combining NFC Type-5 properties with augmented NDEF (NFC Data Exchange Format) and tamper detection, STMicroelectronics’ ST25TV512C and ST25TV02KC tags let developers leverage NFC contactless communication in new and imaginative ways for applications in consumer engagement, brand recognition, supply-chain management, and access control.

With the added benefit of tamper detection in the ST25TV02KC-T variant, use cases that need to verify the integrity of assets can leverage the enhanced flexibility of Augmented NDEF communication. All devices feature state-of-the-art protection services, which include a 64-bit encrypted password with failed-attempt counter for data safety, TruST25 digital-signature services to verify die authenticity, and untraceable and kill modes to protect user privacy.

Developers working with the ST25TV512C and ST25TV02KC tags can deliver high-quality solutions to market quickly, taking advantage of ST’s established ST25 ecosystem that includes extensive software libraries, example applications, and reference implementations.

Building on ST’s experience in NFC technology, the tags deliver advantages such as extended communication range with superior reliability. In addition, retaining the same chip capacitance as the previous product generation helps to simplify the design of the antenna. The tags operate from -40°C to 85°C and integrate a configurable EEPROM with 60-year data retention, which is the highest value available among major NFC suppliers.

The ST25TV512C (ST25TV512C-AFG3) and ST25TV02KC (ST25TV02KC-TFG3 & ST25TV02KC-AFG3) are available as sawn and bumped wafer or packaged in UFDFPN5. Pricing starts from $0.08 for the ST25TV02KC-AFG3, for orders of 1000 pieces.
