HITAG 2 Transponder IC

Product Details


  • Identification transponder for use in contactless applications
  • Operating frequency 125 kHz
  • Data transmission and energy supply via RF link, no internal battery
  • Reading distance same as writing distance
  • Non-volatile memory of 256 bits (128-bit user data and 128-bit control data/secret memory) organized in 8 pages, 4 bytes each
  • 10 years non-volatile data retention
  • 100000 erase/write cycles
  • Selective read/write protection of memory content
  • Two coding schemes for read operation: Biphase and Manchester coding
  • Effective communication protocol with outstanding data integrity check
  • Mutual authentication function
  • Read/write mode allows:
    • Plain data transmission (password mode)
    • Encrypted data transmission (crypto mode)
  • In read/write mode multi-tag operation possible because of special HALT-function
