Introduction

The PRH601 is an integrated RF Identification reader module for contactless

communication at 13.56 MHz and 125 kHz. It implements an additional 32-bit ARM

CortexM0 microcontroller core.

The package contains three dies:

1. LPC1227FBD48/301

2. HTRC11001T/02EE

3. CLRC66301HN1

Not all pins of the LPC1227 specified in the data sheet are available at the reader module.

Please refer to Section 9 “Pinning information”.

The device does not implement any interconnection inside the package. This enables

access to all signals during system development. The device can be replaced by a

integrated reader module PRH601 if no 125 kHz functionality is required. A re-design of

the PCB is not required in this case.

General description

2.1 HTRC110

The HITAG Reader Chip HTRC110 is intended for use with transponders, which are

based on the HITAG silicon (HT1ICS3002x or HT2ICS2002x). 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 new Adaptive Sampling Time technique (AST).
