UCODE® 7/7m

SL3S1204

NXP’s UCODE 7 is a product of the UCODE product family and can be used in several RFID tagging applications.

UCODE® 7m is a derivative of the UCODE 7 and features a 32-bit User Memory on top of UCODE 7.

Particularly well suited for inventory management application, like e.g Retail and Fashion, with its RF performance for any given form factor, UCODE 7 enables long read distance and fast inventory of dense RFID tag population. With its broadband design, it offers the possibility to manufacture true global RFID label with great performance over worldwide regulations.

The device also provides a pre-serialized 96-bit EPC and a Parallel encoding feature. For applications where the same 58-bit Stock Keeping Unit (SKU) needs to be encoded on multiple tags, at the same time, a combination of both features improves and simplifies the tag initialization process.

On top UCODE 7 offers a Tag Power Indicator for RFID tag initialization optimization and a Product Status Flag for Electronic Article Surveillance (EAS) application.

  • Very fast bulk encoding
  • Product identification through unalterable extended TID range, including a 48-bit serial number
  • Reliable operation in dense reader and noisy environments through high interference rejection
  • High sensitivity enables smaller and cost efficient antenna designs for the same retail category
  • Tag Power Indicator features enables very high density of inlay on rolls without crosstalk issues during writing/encoding
  • The different input capacitance for the single slit antenna solution provides an additional possibility in tuning of the impedance for the antenna design
  • 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
  • Pre-serialization of the 96-bit EPC
  • Extremely fast encoding of the EPC content
  • All mandatory commands of EPC global specification V.1.2.0 are implemented including:
    • (Perma)LOCK
    • Kill Command
  • The following optional commands are implemented in conformance with the EPC specification:
    • Access
    • BlockWrite (2 words, 32-bit)
  • Product Status Flag bit: enables the UHF RFID tag to be used as EAS (Electronic Article Surveillance) tag without the need for a back-end database.
  • Tag Power Indicator: enables the reader to select only ICs/tags that have enough power to be written to.
  • Parallel encoding: allows for the ability to bring (multiple) tag(s) quickly to the OPEN state and hence allowing single tags to be identified simply, without timing restrictions,or multiple tags to be e.g. written to at the same time, considerably reducing the encoding process
