2 Key benefits
2.1 End user benefit
  • Extended user memory of up to 2-kbit
  • Brand protection feature using digital signature
  • Long read/write ranges due to leading edge chip sensitivity
  • Reliable operation in dense reader and noisy environments through high interference rejection
2.2 Antenna design benefits
  • High sensitivity enables smaller and cost efficient antenna designs
  • Selected chip impedance enables re-use of antenna designs from UCODE 7
2.3 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
3 Supported features
  • All mandatory commands of EPCglobal v1.2.0 specification are implemented
  • The following optional commands are implemented:
    • Access
    • BlockPermalock (block size of 256-bit)
    • 32-bit BlockWrite
  • Implemented custom commands and features:
    • Untraceable
    • ReadSignature
    • 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 data base.
    • 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

UCODE 7xm can be used in combination with readers compliant with EPCglobal v1.2.0 standard. For access to full UCODE 7xm family functionality firmware upgrade of the reader may be necessary.
