The Hitag Reader Chip HTRC110 is intended for use with transponders, which are based on the
HITAG silicon (HT1ICS30 02x or HT2ICS20 02x). (E.g. the HITAG 2 stick HT2DC20 S20 may be
operated with the use of the Reader Chip). In addition the IC supports other 125kHz transponder
types using amplitude modulation for the write operation and AM/PM for the read operation. The
receiver parameters (gain factors, filter cutoff frequencies) can be optimized to system and trans-
ponder requirements. The HTRC110 is designed for easy integration into RF-identification readers.
State-of-the-art technology allows almost complete integration of the necessary building blocks. A
powerful antenna driver/modulator together with a low-noise adaptive sampling time demodulator,
programmable filters/amplifier and digitizer build the complete transceiver unit, required to design
high-performance readers. A three-pin microcontroller interface is employed for programming the
HTRC110 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 caused severe problems in envelope detector sys-
tems, resulting in the need of very low tolerance reader antennas. These problems are solved by the
new Adaptive Sampling Time technique (AST).
