1.1 Memory
  • 32-bit User Memory
  • Up to 128-bit of EPC memory
  • Supports self pre-serialization for 96-bit EPC
  • 96-bit Tag IDentifier (TID) factory locked
  • 48-bit unique serial number factory-encoded into TID

2 Key benefits
2.1 End user benefit
  • Long READ and WRITE ranges due to leading edge chip sensitivity
  • 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
2.2 Antenna design benefits
  • High sensitivity enables smaller and cost efficient antenna designs for the same retail
  • 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 enables a finer
    tuning of the impedance for the antenna design
2.3 Label 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 anytime its EPC serial number is erased
  • Extremely fast encoding of the EPC content
3 Supported features
  • All mandatory commands of EPC global specification V.1.2.0 are implemented

    • (Perma)LOCK
  • The following optional commands are implemented in conformance with the EPC

    • 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 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

AAll supported features of UCODE 7m can be activated using standard EPCglobal READ / WRITE / ACCESS / SELECT commands. No custom commands are needed to take advantage of  all the features in case of unlocked EPC memory. The parallel encoding feature may  however require a firmware upgrade of the reader to use its full potential.
