FEATURES
GENERAL DESCRIPTION
The HITAG
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).

2001 Oct 01
Identification transponder for use in contactless
applications
Operating frequency 125 kHz
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
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
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).
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
– Public mode C (PIT compatible mode).
Special features:
– User defined write protection
– Unique 32-bit serial number for each transponder
– Read-only emulation function
– Encrypted data transmission possible.

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.
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.
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.
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.
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.
Data transmission from the reader to the HT2DC20S20
uses Binary Pulse Length Modulation (BPLM).
