Features

Key features

  • UHF RFID Gen2 tag chip according to EPCglobal v1.2.0 with 128-bit EPC memory
  • Memory read protection
  • Integrated Product Status Flag (PSF)
  • Tag tamper alarm
  • RF field detection
  • Digital switch
  • Data transfer mode
  • Real Read Range Reduction (Privacy Mode)
  • External supply mode where both the READ & WRITE range are boosted to -27 dBm

Memory

  • 128-bit of EPC memory
  • 64-bit Tag IDentifier (TID) including 32-bit factory locked unique serial number
  • 32-bit kill password to permanently disable the tag
  • 32-bit access password to allow a transition into the secured state
  • Data retention: 20 years
  • Broad international operating frequency: from 840 MHz to 960 MHz
  • Long read/write ranges due to extremely low-power design
  • Reliable operation of multiple tags due to advanced anti-collision
  • READ protection
  • WRITE Lock
  • Wide specified temperature range: -40 °C up to +85 °C

End-user benefit

  • Prevention of unauthorized memory access through read protection
  • Indication of tag tampering attempt by use of the tag tamper alarm feature
  • Electronic device configuration and / or activation by the use of the digital switch / data transfer mode
  • Theft deterrence supported by the PSF feature (PSF alarm or EPC code)
  • Small label sizes, long read ranges due to high chip sensitivity
  • Product identification through unalterable extended TID range, including a 32-bit serial number
  • Reliable operation in dense reader and noisy environments through high interference suppression

Antenna design benefits

  • High sensitivity enables small and costs efficient antenna designs
  • Low Q-Value eases broadband antenna design for global usage

Label manufacturer benefit

  • Consistent performance on different materials due to low Q-factor
  • Ease of assembly and high assembly yields through large chip input capacitance
  • Fast first WRITE of the EPC memory for fast label initialization

Custom commands

  • PSF Alarm
  • Built-in PSF (Product Status Flag), enables the UHF RFID tag to be used as EAS tag (Electronic Article Surveillance) tag without the need for a back-end database
  • Read Protect
  • Protects all memory content including CRC16 from unauthorized reading
  • ChangeConfig

  • Configures the additional features of the chip like external supply mode, tamper alarm, digital switch, read range reduction or data transfer

    • The UCODE G2iL is equipped with a number of additional features and custom commands. Nevertheless, the chip is designed in a way standard EPCglobal READ/WRITE/ACCESS commands can be used to operate the features. No custom commands are needed to take advantage of all the features in case of unlocked EPC memory.
