HTRC11001T

HITAG⁽¹⁾ is the family name of the reader chip HTRC11001T to use with transponders which are based on the HITAG tag ICs (HT1ICS3002x or HT2ICS2002x).

The receiver parameters (gain factors and filter cut-off frequencies) can be optimized to system and transponder requirements. The HTRC11001T is designed for easy integration into RF identification readers.

State-of-the-art technology of HTRC11001T allows almost complete integration of the necessary building blocks. A powerful antenna demodulator and driver, together with a low-noise adaptive sampling time demodulator, a programmable filter, amplifier and digitizer, build the complete transceiver unit, required to design high-performance readers.

A three-pin microcontroller interface is employed for programming the HTRC11001T as well as for the bidirectional communication with the transponders. The three-wire interface can be changed into a two-wire interface by connecting the data input and the data output.

Tolerance dependent zero amplitude modulation will cause severe problems in envelope detector systems, resulting in the need of very low tolerance reader antennas. These problems are solved by the new Adaptive Sampling Time (AST) technique of HTRC11001T.
