Integrated Circuit HITAG Reader Chip IC HTRC11001T programmable

Quick Detail:

HITAG reader chip

Description:

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 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.

Applications:

• Combines all analog RFID reader hardware in one single chip

• Optimized for HITAG transponder family

• Robust antenna coil power driver stage with modulator

• High performance adaptive sampling time AM/PM demodulator (patent pending)

• Read and write function

• On-chip clock oscillator

• Antenna rupture and short circuit detection

• Low power consumption

• Very low power standby mode

• Low external component count

• Small package SO14.
