Product overview

Description

ST25TN512 and ST25TN01K devices are NFC Forum Type 2 tag IC with TruST25 digital signature, Augmented NDEF, and privacy features.

The RF interface is compliant with ISO/IEC 14443-2 and 14443-3 Type A standards, and NFC Forum Type 2 tag specification. Thanks to its internal tuning capacitance and harvesting of operating power from RF field provided by the NFC poller, it simply operates with an antenna and without additional component.

The embedded electrically erasable programmable memory (EEPROM) can be written with a NDEF message conforming to NFC Forum specification offering native tap with all NFC-enabled phones.

The Augmented NDEF feature allows the tag to answer dynamic NDEF message without modification of the EEPROM by the user.

The TruST25 digital signature helps fighting against counterfeiting.

The kill feature guarantees user privacy by permanently muting the tag with a simple software procedure.

In this document, the term ST25TN refers interchangeably to ST25TN512 or ST25TN01K.
