General description

The CLRC632 is a member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This family of reader ICs provide:

• outstanding modulation and demodulation for passive contactless communication
• a wide range of methods and protocols
• a small, fully integrated package
• pin compatibility with the MFRC500, MFRC530, MFRC531 and SLRC400

All protocol layers of the ISO/IEC 14443 A and ISO/IEC 14443 B communication standards are supported provided:

• additional components, such as the oscillator, power supply, coil etc. are correctly applied.
• standardized protocols, such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B anticollision are correctly implemented

Using this NXP Semiconductors device according to ISO/IEC 14443 B may infringe third party patent rights.

The CLRC632 supports contactless communication using MIFARE higher baud rates. The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for compatible transponder signals.

The digital module, manages the complete ISO/IEC 14443 standard framing and error detection (parity and CRC). In addition, it supports the fast MIFARE security algorithm for authenticating the MIFARE products.

All layers of the I-CODE1 and ISO/IEC 15693 protocols are supported by the CLRC632. The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for I-CODE1 and ISO/IEC 15693 compatible transponder signals. The digital module handles I-CODE1 and ISO/IEC 15693 framing and error detection (CRC).

The internal transmitter module (Section 9.9 on page 31) can directly drive an antenna designed for a proximity operating distance up to 100 mm without any additional active circuitry.

A parallel interface can be directly connected to any 8-bit microprocessor to ensure reader/terminal design flexibility. In addition, Serial Peripheral Interface (SPI) compatibility is supported.
