NXP - HITAG Transponder IC

NXP - HITAG Low-Frequency Transponder IC

NXP HITAG products support the low-frequency (LF) RFID market—delivering high reliability, robust performance and safe data transmission. The HITAG transponder ICs operate at a frequency range of 100 to 150 kHz and offer the advantage of operating in harsh environments. 

NXP - HITAG 2 Transponder IC

HITAG 2 based transponders are highly integrated and do not need any additional components beside the HITAG 2 transponder IC and the external coil. Data are transmitted bidirectionally, in half duplex mode, between Read Write Device (RWD) and HITAG transponder IC. To achieve a main stream security, data may be transmitted enciphered. HITAG 2 transponder IC offer a memory of 256 bit.

Custom specific configuration of the transponder IC is possible by using the configuration page. The configuration page allows the selection of different modes and access possibilities and also the configuration of the memory. The pages of the memory can be protected against read or write access by setting corresponding memory flags.

The HITAG 2 transponder IC provides - besides password and crypto mode - the following three standard read only modes, that can be configured using the configuration byte: 
  • public-mode A 
  • public-mode B (animal identification, according to ISO 11784 and ISO 11785)
  • public-mode C (PIT compatible mode PCF793x)
  • 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 of 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
  • Emulation of standard industrial read-only transponders:
    public-mode A (MIRO and transponders from μEM (H400x))
    public-mode B (according to ISO 11784 and ISO 11785 for animal identification)
    public-mode C (PIT compatible mode)
