 Hitag 1
Description
The HT1 DC20 S30, based on the HITAG 1 IC, is a high performance transponder for bi-directional data transmission in half duplex mode.
Data are stored in the transponder in a non -volatile memory (EEPROM). The transponder acts as a passive device, thus not having the need for any internal power supply (battery).
It derives power from the magnetic component of the RF carrier frequency generated by the reader. Data is transmitted by modulating this carrier.
The HT1 DC20 S30 is dedicated for use in secure access systems where the transponder and the reader have to identify each other.
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.
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 HT1 DC20 S30 uses binary pulse length modulation (BPLM).
The anticollision feature of the transponder allows to operate several transponders simultaneously in thefield of the reader antenna. To use that feature, the reader needs to have implemented the anticollision protocol and mustbe able to detect bit-collisions. (e.g. the Philips HTRM800 long range reader module includes the anticollision protocol.)
Features
 > Complete identification transponder for use in contactless applications
 > Operating frequency 125 kHz
 > Data transmission and supply energy via RF link, no internal battery
 > Low power EEPROM technology for writing distance that equals reading distance
 > Total memory size 2048 bit
 > Parts of memory can be write protected by the user
 > Effective communication protocol with outstanding data integrity check
 > Secure mutual authentication function
 > Encrypted data transmission
 > Anticollision protocol for handling of multiple transponders inside the field of the reader antenna.

 Hitag 2
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).
Features
 > Identification transponder for use in contactless applications
 > Operating frequency 125 kHz
 > Data transmission and energy supply via RF link, no internal battery
 > Reading distance same as writing distance
 > Non-volatile memory of 256 bits (128 bit user data and 128 bit control data/secret memory) organized in 8 pages, 4 Bytes each
 > 10 years non-volatile data retention
 > 100 000 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 (MIRO and transponders from μEM (H400x))
   - Public Mode B (according to ISO 11784 and ISO 11785 for animal identification)
   - Public Mode C (PIT compatible mode)

 Hitag S 256/2048
Description
HITAG-S ICs feature a new,innovative,ultra low power design specifically designed to provide the longer reading ranges required for completely automated livestock tracking on today's large farms.
With a standard ISO 11784/85 gate reader,livestock tagged with HITAG-S tags can be automatically identified,even in large numbers.
Adding ISO 14223/1 also enables vaccination data to be stored directly on the tag.This operation can be restricted to authorized veterinarians.As all the animals' data is then available directly and off-line,stock tracking on industrial farms as well as reliable import/export control around the world becomes transparent,verifiable,and affordable.
Features
 > Three memory options (32 Bit UID, 256 Bit, 2048 Bit)
 > More than 100 000 erase/write cycles
 > 10 years non-volatile data retention
 > Frequency range 100-140 kHz
 > CRC data integrity check
 > Data Rates (Tag to Reader): 2.0kbits/s,4.0kbits/s,8.0kbits/s
 > Data Rate (Reader to Tag): 5.2kbits/s
 > Secure Memory Lock functionality
 > 32 Bit Unique Identification Number (UID)
 > 48 bit secret key based encrypted authentication
Advantages
 > Small die size:fits into injectable glass tubes
 > Long read/write operating range
 > Compatible with HITAG 1 and HITAG 2 reader infrastructure
 > Selectable operating modes provide compatibility with existing reader infrastructures
 > ISO 11784/85 and ISO 14223/1 compliant
 > Compliant to German Waste Management Standard (BDE)
 > Compliant to German Pigeon Race Standard
