2 GENERAL DESCRIPTION
The HT2DC20S20 is a high performance transponder for bi-directional transmission in half
duplex mode between read/write device and transponder.
Data are stored in the transponder in a non-volatile memory (EEPROM). The transponder
requires no internal power supply; it derives its power from the magnetic component of the RF
carrier frequency generated by the reader. Data are transmitted by modulating this carrier.
The HT2DC20S20 is dedicated for use in secure access systems where the transponder and the
reader have to identify each other. The choosable use of cryptography enables highest data
security. Providing several operating modes (password, crypto, standard read only modes) the
versatile transponder can be used in various applications. The possible use of an installed reader
base for read only transponders makes the additional use of HT2DC20S20 or the replacement of
read only transponders by HT2DC20S20 very easy.
The HALT-command can be used after finishing data exchange to reach the halt-state. In this
state the transponder is muted. This feature can be used to have steady RF field where single
transponders are collected one by one. Each transponder is operated and then disabled so it does
not interfere with the next transponder. The halt-state can only be exited by switching
off/removing the magnetic field.
The EEPROM has a capacity of 256 Bits and is organized in 8 pages of 4 Bytes. The 8 pages are
split up into 4 pages containing user data and into 4 pages for control of the memory access and
for authentication purposes.
The pages of the transponder memory can be protected against read or write access by setting
corresponding memory flags.
Absorption modulation is used to transmit data from the transponder to the reader. The
transponder absorbs the magnetic field, which hence modulates the current in the reader antenna.
Data transmission to the HT2DC20S20 uses binary pulse length modulation (BPLM).

5.2 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 the Configuration Byte is read from the EEPROM
of the transponder.
If you change the configuration, keys or passwords, you have to place the
transponder directly on the antenna (0-distance)! In order to avoid any errors do not
move the transponder during this write process and be sure that you are in a safe
environment without electrical noise.
5.2.1 Modes of Operation
The HT2DC20S20 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.
Public Mode A (Manchester):
Read only mode emulating Philips MIRO transponders resp. µEM H400x transponders.
The 64 bits of the user Pages 4 and 5 are cyclically transmitted to the read/write device.
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 read/write device.
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
read/write device.

HITAG 2 Transponders
Product Specification 3.0

5.2.2 Status Flow
After entering the RF-field the transponder 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 read/write
device.
By issuing the command to start the authentication during the waiting time also public mode
transponders can be brought into the authorized state.

5.4 Definition of Passwords and Keys
Keys are cryptographic codes, which determine data encryption during data transfer between
read/write device and transponder. They are used to select a HT2DC20S20 transponder 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 read/write device.
Passwords are needed to select a HT2DC20S20 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 read/write device.
Password TAG:
Password that the transponder sends to the read/write device and which
may be verified by the latter (depending on the configuration of the
read/write device).
Password RWD:
Password that the read/write device 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 read/write device and on the transponder have to be identical pairs.

and a Transport Key. They can be written to, which means that they can be changed (see also
Chapter “Configuration of Delivered HT2DC20S20 Transponders“).
ATTENTION: Passwords and Keys only can be changed if their current values are known!
