Features & Applications

The HITAG Reader Chip HTRC110 is intended for use with transponders, which are
based on NXP Semiconductors based HITAG transponder ICs.
In addition the IC supports other 125 kHz 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 transponder
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 systems, resulting in the need of very low tolerance reader antennas. These
problems are solved by the Adaptive Sampling Time technique (AST)
