1. General description
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)
2. Features and benefits
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
Emulation of standard industrial read-only transponders:

6. Block diagram
The HITAG 2 transponder IC requires no external power supply. The contactless interface
generates the power supply and the system clock via the resonant circuitry by inductive
coupling to the RWD. The interface also demodulates data transmitted from the RWD to
the HITAG 2 transponder IC, and modulates the magnetic field for data transmission from
the HITAG 2 transponder IC to the RWD.
Data are stored in a non-volatile memory (EEPROM). The memory has a capacity of
256 bit and is organized in pages.

7.2 Memory map
The 256 bit memory area of the HITAG 2 transponder IC is divided into 8 pages. Each
page has a size of 32 bits.
Depending on the operation mode (crypto mode/password mode) the memory is
organized as described in the following:
