SL3S5002N0FUD

Click over video to play

The secure UCODE DNA RAIN RFID (UHF) tag IC supports use cases that require long read ranges of up to 15 meters. The IC combines advanced contactless performance with cryptographic security and enables a variety of Smart City applications, such as asset tagging, automatic vehicle identification, access control, and supply chain management.

The security of the chip is based on a 128-bit AES key which is stored in the IC hardware and performs cryptographic authentication checks. The UCODE DNA IC is designed in compliance with standards for worldwide interoperability, namely the GS1™ UHF RFID Gen2 v2.0 (Annex N, Tag Alteration (Authenticate)), and ISO/IEC 29167-10 for proof of origin based on AES (Advanced Encryption Standard).

Antenna design benefits

  • High sensitivity enables smaller and cost efficient antenna designs
  • Selected chip impedance enables re-use of antenna designs from UCODE 7

Label / module manufacturer benefit

  • Large RF pad-to-pad distance to ease antenna design
  • Symmetric RF inputs are less sensitive to process variation
  • Single-slit antenna for a more mechanically stable antenna connection
  • Automatic self pre-serialization of the 96-bit EPC
  • Extremely fast encoding of the EPC content
