Hitag 1 Card

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).

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 resonant frequency generated by the reader. Data is transmitted by modulating this resonant frequency.

The HT1DC20S30 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.

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.

Data transmission from the reader to the HT1DC20S30 uses Binary Pulse Length Modulation (BPLM).

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.
