Product overview
Description
The ST25TA-E devices are NFC/RFID tag ICs with solid security and privacy features.
The ST25TA-E devices hold a unique off-chip generated digital signature through TruST25 (a set of software and procedures) used to prove the origin of the chip UID in identification detection.
The ST25TA-E devices also generate on-chip digital signatures dynamically through Edge TruST25 services to prove the origin of the product in ownership detection and associated data. They also embed custom certificates for enrollment verification.
The Augmented NDEF feature is an automatic contextual NDEF message service that allows tags to react to dynamic content without user interaction.
The ST25TA-E devices have a configurable flash memory with 25 years of data retention and work with a 13.56 MHz short range RFID reader or an NFC phone.
The contactless interface is compliant with the ISO/IEC 14443 standard and NFC Forum Type 4 tag specification.
