The NTAG 22x DNA line is powered by SUN (Secure Unique NFC) message authentication with AES cryptography and status awareness using conductance or capacitance. The product’s application space is virtually unlimited, since it can be used as an authentication tag, an anti-tampering tag, or a simple battery-free sensing tag, expanding the reach of smart, trusted IoT objects.

Key Features

  • Full NFC interoperability – ISO/IEC 14443-A communication, NFC Forum Type 2 Tag
  • Standard AES-128 cryptography and CC EAL3+ certification
  • SUN (Secure Unique NFC) message authentication for advanced data protection within NFC (NDEF) read operation
  • User memory of 144 bytes (NTAG 223 DNA) or 208 bytes (NTAG 224 DNA)
  • User memory protected by password (NTAG 223 DNA) or 3-pass mutual authentication (NTAG 224 DNA)
  • Customizable Originality Signature (48-byte based on ECC) to validate tag origin
  • Conductive or capacitive tamper-protection mechanisms (NTAG 22x DNA StatusDetect)
  • Capacitive sensing interface to external capacitor to measure changes in environmental conditions, e.g. humidity, pressure (StatusDetect)
  • 7-byte Unique ID
  • Automatic NFC tap counter
  • On-chip assembly of item URLs with ASCII mirrors (UID, counter, tamper status, CMAC)
  • 50 pF input capacitance for compact antenna design
