HITAG 1 stick transponder
HT1DC20S30
FEATURES
• Complete identification transponder for use in
contactless applications
• Operating frequency 125 kHz
• Data transmission and supply energy via RF link, no
internal battery
The transponder acts as a passive device, thus not having
the need for any internal power supply (battery).
• Low power EEPROM technology for writing distance
that equals reading distance
It derives power from the magnetic component of the
RF resonant frequency generated by the reader. Data is
transmitted by modulating this resonant frequency.
• Total memory size 2048 bits
• Parts of memory can be write protected by the user
The HT1DC20S30 is dedicated for use in secure access
systems where the transponder and the reader have to
identify each other.
• Effective communication protocol with outstanding data
integrity check
• Secure mutual authentication function
The EEPROM has a capacity of 2048 bits and is
organised in 64 pages. Access is provided either in page
mode or in block mode, where 1 block includes 4 pages.
• Encrypted data transmission
• Anticollision protocol for handling of multiple
transponders inside the field of the reader antenna
Data transmission from the HT1DC20S30 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.
• Special features:
– User defined write protection
– Unique 32-bit serial number for each transponder
– Encrypted data transmission possible.
Data transmission from the reader to the HT1DC20S30
uses Binary Pulse Length Modulation (BPLM).
GENERAL DESCRIPTION
The anticollision feature of the transponder allows to
operate several transponders simultaneously in the field of
the reader antenna. To use that feature, the reader needs
to have implemented the anticollision protocol and must be
able to detect bit-collisions (e.g. the Philips HTRM800 long
range reader module includes the anticollision protocol.
The HITAG(1) stick transponder HT1DC20S30, based on
the HITAG tag IC, is a high performance transponder for
bi-directional data transmission in full-duplex mode. Data
is stored in the transponder in a non-volatile memory
(EEPROM).

Related documents
When writing to page 1 (configuration page) we strongly
recommend to carefully follow the instructions in the
document “HT1 Transponder Family Communication
Protocol Reader - HITAG 1 Transponder”. In particular,
overwriting the reserved bits in configuration page 1 may
lead to reduced reading range of the HT1DC20S30.
For additional information on the functional description of
the HT1DC20S30, in particular the protocol between
reader and transponder please refer to the document “HT1
Transponder Family Communication Protocol Reader HITAG 1 Transponder” (document number HT038522).
