1 FEATURES 2 GENERAL DESCRIPTION Combines all analogue RFID reader hardware in a single The Hitag Reader Chip HTRC110 is intended for use chip with transponders which are based on the HITAG silicon (HT1ICS30 02x or HT2ICS20 02x). (E.g. the · Optimized for HITAG transponder family HITAG 2 stick HT2DC20 S20 may be operated with the · Robust antenna coil power driver stage with modulator use of the Reader Chip). In addition the IC supports other 125kHz transponder types using amplitude modu· High performance adaptive sampling time AM/PM lation for the write operation and AM/PM for the read demodulator (patent pending) operation. The receiver parameters (gain factors, filter · Read and write function cutoff frequencies) can be optimized to system and transponder requirements. The HTRC110 is designed · On-chip clock oscillator for easy integration into RF-identification readers. · Antenna rupture and short circuit detection State-of-the-art technology allows almost complete integration of the necessary building blocks. A powerful · Low power consumption antenna driver/modulator together with a low-noise · Very low power stand-by mode adaptive sampling time demodulator, programmable filters/amplifier and digitizer build the complete trans· Low external component count ceiver unit, required to design high-performance · Small package (SO14) 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 new Adaptive Sampling Time technique (AST). 3 ORDERING INFORMATION TYPE NAME HTRC110 01T/02EE HTRC110 01T/03EE DESCRIPTION Hitag Reader IC, Tube Hitag Reader IC, Reel ORDERING NUMBER 9352 600 91112 9352 600 92118
