1. Introduction
HITAG 2 is part of the universal and powerful product line of NXP Semiconductors
125 kHz HITAG family. The contactless read/write system that works with passive
transponders is suitable for various applications. Inductive coupling allows to achieve big
reading ranges.
The HITAG product family is used in the proximity area (operating range up to about
200 mm) as well as in the long range area (operating range up to about 1000 mm).
2. 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.
HTAG 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)

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.

9.3 Definition of passwords and keys
Keys are cryptographic codes, which determine data encryption during data transfer
between RWD and transponder IC. Keys are used to select a HITAG 2 transponder IC in
Crypto Mode. The 16 bit KEY HIGH and 32 bit KEY LOW form one 48 bit key which has to
be identical on both the transponder and the RWD.
Passwords are needed to select a HITAG 2 transponder in Password Mode. There is one
pair of passwords (Password TAG, Password RWD) which has to be identical both on the
transponder and the RWD.
Password TAG:
Password RWD:
Password that the transponder sends to the RWD and which may be
verified by the latter (depending on the configuration of the RWD).
Password that the RWD sends to the transponder and which is checked for
identity by the latter.
It is important that the following values are in accordance with each other, i.e. the
respective data on the RWD and on the transponder have to be identical pairs.

The passwords and keys are predefined by NXP Semiconductors by means of defined
transport passwords and a transport key. They can be written to, which means that they
can be changed (see also Chapter "Configuration of Delivered HITAG 2 Transponders"
Section 9.4.3.3).
ATTENTION: Passwords and Keys only can be changed if their current values are known!

9.4 Operation Modes and Configuration
With the Configuration Byte the operation mode and the access rights to the memory can
be selected. During Power-Up of the transponder IC the Configuration Byte is read from
the memory.
In case keys or passwords are changed, the transponder should be placed directly
(0-distance) on the antenna of the RWD! In order to avoid any errors the
transponder must not be moved during this write process. The programming
should take place in a safe environment without electrical noise.
9.4.1 Modes of operation
The HITAG 2 can be operated in several modes.
Crypto Mode
Mode for writing or reading the transponder with encrypted data transmission.
Password Mode
Mode for writing or reading the transponder with plain data transmission after password
check.
Public Mode A (Manchester)
Read only mode. The 64 bits of the User Pages 4 and 5 are cyclically transmitted to the
RWD.
Public Mode B (Biphase)
Read only mode according to ISO standards 11784 and 11785 for animal identification.
The 128 bits of the User Pages 4 to 7 are cyclically transmitted to the RWD.
Public Mode C (Biphase)
Read only mode emulating the read operation of the PCF793X (with a slightly different
Program Mode Check).
In the Public Mode C the 128 bits of the User Pages 4 to 7 are cyclically transmitted to the
RWD.

9.4.2 Status flow
Fig 5. Status flow
After entering the RF-field the transponder enters the Wait Mode and waits for a command
to start the authentication.
After issuing this command the mutual authentication takes place, followed by read- and
write commands.
In password mode the data transfer occurs plain, in crypto mode data are encrypted.
The Halt Mode can be entered for muting a transponder.
If the transponder is configured in one of the public modes, these modes are entered
automatically after a certain waiting time and data pages are sent cyclically to the RWD.
By issuing the command to start the authentication during the waiting time also public
mode transponders can be brought into the authorized state.

9.5 Electromagnetic characteristics
9.5.1 Magnetic flux densities
Since magnetic coupling is used for the data transmission between transponder and RWD
the magnetic field is the most important attribute. Figure 7 shows the direction of the
magnetic field lines with the transponder placed in the antenna field.

9.6 Data transmission: transponder → RWD
9.6.1 Coding
Load modulation is used, when sending data to the RWD. To force the absorption of the
magnetic field, the transponder in principle turns on/off an internal resistor. With the
resistor turned on, the physical state is named modulator ON (loaded) otherwise
modulator OFF (unloaded).
Two different codes are used for the transmission of data to the read/write device:

9.7 Data transmission: RWD → transponder
9.7.1 Coding
Data are transmitted to the transponder by switching on/off the current through the
antenna. When the current is switched off, the physical state is named low field, otherwise
high field.
Binary puls length modulation (BPLM) is used to encode the data stream.
All coded data bits and the stop condition start with a low field of length tlow
.
Afterwards the field is switched on again.
• '0' and '1' can be distinguished by the duration of T[0] and T[1].
• The end of the data transmission is characterized by a stop condition.
Figure 11 shows the data transmission from the RWD to the transponder.

9.8 Switching the transmission direction
When switching between receiving and sending, the RWD has to consider time frames, in
which transmission of data is not allowed:
• tWAIT1
:
:
When receiving the last bit from the RWD, the transponder waits before
answering.
• tWAIT2
After receiving the last bit from the transponder, the RWD has to wait before
sending data. Data transmitted to the transponder within twait, will not be
recognized by the transponder.

9.8.1 Data integrity using the HITAG 2
For data transmission between RWD and transponders the HITAG 2 transponder IC
supports special commands to increase data integrity.
Using additional inverted data transmission for commands, addresses as well as read
data, utmost data integrity is achieved.
For write transmissions read after write is recommended. See also Section 10 “Command
set and timing”

2. Instructions for the communication itself
10.1 Data flow: RWD ↔ transponder
Please note that the transponder IC memory works like a FIFO (First-In-First-Out)
memory. Therefore the order of the bits transferred is as described in the example below:
Write: Bit 31 is sent first to the transponder.
Read: Bit 31 is sent first to the RWD.

The instruction START_AUTH cannot be repeated, because at the same time the crypto
unit is initialized. A second START_AUTH resets the state machine. Therefore the
transponder only responds to every second START_AUTH.
After the transponder has sent the serial number, the RWD sends a 32 bit Pseudo
Random Number (PRN) and a 32 bit secret datastream to the transponder. If the secret
datastream corresponds with the secret datastream on the transponder, Page 3 of the
transponder (8 bit configuration, 24 bit password transponder) is transmitted after the 5 bit
header.
With the transponder password in the configuration page the mutual authentication takes
place. Access to the transponder is only possible after this mutual authentication and
password checking routine. Transmission of the password and the following
communication takes place encrypted.
As the information about the configuration of the transponder (password or crypto) is
transmitted with the configuration page, the RWD must know which type of transponder
has to be handled. In one application either crypto transponders or password
transponders are to be handled.
The write instructions are interrupted by the transponder, when the memory supply is too
low during the write operation.

Transponder IC
Public Mode C
With this additional feature a HITAG 2 transponder IC that is configured in Public Mode C
is compatible to the PCF793X (PIT).
After the configuration byte is stored in the logic during power up, and after the
synchronization phase of the state machine, the transponder waits for the instruction
START_AUTH. If the RWD does not send the instruction START_AUTH within 232.5 T0
after power up the transponder begins to send the data in PCF793X mode.
In this mode the transponder cyclically transmits page 4 to page 7 in plain mode to the
RWD without a start sequence as long as the transponder is in the field of the RWD. The
data are transmitted in Biphase Code with a baudrate of 2 KBit/s. Between the 128 bit
data blocks there is a Program Mode Check phase (PMC).

The instruction READ PAGE (2 bits) and the page address (3 bits) are transmitted to the
transponder in normal mode and in inverted mode to secure the data channel from RWD
to transponder. To achieve a higher confidence level, this protocol can be repeated
several times. The logic on the transponder checks if there is a failure in the sequence.
The READ PAGE instruction therefore is 10, 15, 20, ..... bits long. If there is a failure in the
transmission of the sequence the transponder is reset and the communication has to be
started again with START_AUTH. If the transponder receives no more data and there was
no failure in the transmission of the sequence, the transponder answers with the 5 bit
header and the 32 bit data of the addressed page.

more data and there was no failure in the transmission of the sequence, the transponder
answers with the 5 bit header and the 32 bit data of the addressed page. The data are
transmitted inverted to the RWD.
By alternating transmission of the instructions READ PAGE and READ PAGE INVERTED
the data from the transponder to the RWD can be secured at a level that can be chosen
by the user. Additionally check data can be stored in the transponder IC memory with the

32 Bit Data
The instruction WRITE PAGE (2 bits) and the page address (3 bits) are transmitted to the
transponder in normal mode and in inverted mode to secure the data channel from RWD
to the transponder. To achieve a higher confidence level, this protocol can be repeated
several times. The logic on the transponder checks if there is a failure in the sequence.
The WRITE PAGE instruction therefore is 10, 15, 20, ..... bits long. If there is a failure in
the transmission of the sequence the transponder is reset and the communication has to
be started again with START_AUTH. If the transponder receives no more data and there
was no failure in the transmission of the sequence, the transponder answers with the 5 bit
header and an acknowledgement. This acknowledgement consists of the WRITE PAGE
instruction and the page address in normal and inverted mode.
With this procedure the RWD knows, that the data are written to the correct address.
After the address sent from transponder to RWD has been checked, the RWD transmits
32 bit data to the transponder. There is no acknowledgement from the transponder
concerning the success of data programming. This can only be tested by read-after-write.
The READ PAGE command for a read-after-write has to be executed immediately
following the WRITE PAGE command. If the memory supply was too low during
programming (insufficiently programmed cell, data retention not ensured) the read
command is not executed by the transponder (control function!). In this case the
transponder is reset and the user has to start again with a START_AUTH command.

10.3.4 HALT
Transponder IC
With the HALT instruction a selected transponder can be set to the HALT Mode. In this
mode the transponder is muted and does not respond to a START_AUTH from the RWD.
If the transponder is set to HALT Mode after the communication, other transponders within
the field of the antenna can be handled.
If the transponder is in HALT Mode, only a Power-on-reset (POR) enables the
transponder to communicate with the RWD again. This means that the transponder has to
leave the field of the antenna or the field has to be switched off (Reset).
