HITAG 2 stick transponder
HT2DC20S20
FEATURES
• Identification transponder for use in contactless
applications
• Operating frequency 125 kHz
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 is
transmitted by modulating this carrier.
• Data transmission and supply energy via RF link,
no internal battery
• Reading distance same as writing distance
• Non-volatile memory of 256 bits (128 bits user data,
128 bits control data and secret memory) organized in
8 pages, 4 bytes each
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 and standard read-only modes)
the versatile transponder can be used in various
applications.
• Ten years non-volatile data retention
• More than 100000 erase/write cycles
• Selective read/write protection of memory content
• Two coding schemes for read operation: biphase and
Manchester coding
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 and
removing the magnetic field.
• Effective communication protocol with outstanding data
integrity check
• Mutual authentication function
• Read/write mode allows:
– Plain data transmission (password check)
– Encrypted data transmission (crypto mode).
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 and write access by setting corresponding
memory flags.
• In read/write mode multi-tag operation possible because
of special HALT function
• Emulation of standard industrial read-only transponders:
– Public mode A (64 bits read-only)
– Public mode B (according to ISO 11785 for animal
identification)
– Public mode C (PIT compatible mode).
• Special features:
Data transmission from the HT2DC20S20 to the reader
uses Manchester or biphase coding and Amplitude Shift
Keying (ASK) modulation. 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.
– User defined write protection
– Unique 32-bit serial number for each transponder
– Read-only emulation function
– Encrypted data transmission possible.
Data transmission from the reader to the HT2DC20S20
uses Binary Pulse Length Modulation (BPLM).
GENERAL DESCRIPTION
The HITAG(1) stick transponder HT2DC20S20 is a high
performance transponder for bi-directional transmission in
full-duplex between the read and write device and the
transponder.
Data is stored in the transponder in a non-volatile memory
(EEPROM).

FUNCTIONAL DESCRIPTION
Memory organization
Operating modes
With the configuration byte, the operating mode and the
access rights to the memory can be selected.
The memory of the transponder consists of 256 bits
EEPROM memory and is organized in 8 pages with 32 bits
each.
During power-up of the transponder the configuration byte
is read from the EEPROM of the transponder.
Depending on the operating mode the EEPROM is
organized as described in Table 1.
The HT2DC20S20 can operate in several modes:
• Crypto mode
Mode for writing or reading the transponder with
encrypted data transmission.

Status flow
Configuration
After entering the RF field the transponder waits for a
command to start the authentication (see Fig.2). After
issuing this command the mutual authentication takes
place, followed by read and write commands.
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.
In the password mode the data transfer occurs plain and in
the crypto mode data are encrypted.
The configuration byte is represented by the first 8 bits of
page 3 of the transponder memory (see Table 2).
The halt state 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
and 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.

Definition of keys and passwords
• Password RWD
Password that the read and write device sends to the
transponder and which is checked for identity by the
latter.
Keys are cryptographic codes, which determine data
encryption during data transfer between the read and write
device and the transponder. They are used to select a
HT2DC20S20 transponder in the 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
and write device.
It is important that the following values are in accordance
with each other, i.e. the respective data on the read and
write device and on the transponder have to be identical
pairs.
Passwords are needed to select a HT2DC20S20
transponder in the password mode. There is one pair of
passwords (password TAG and password RWD) which
has to be identical both on the transponder and the read
and write device:
The keys and passwords are predefined by Philips by
means of defined transport passwords and a transport
key. They can be written to memory, which means that
they can be changed (see also Section “Configuration of
delivered transponders”).
• Password TAG
Remark: keys and passwords only can be changed if their

device).
