1. Describe

This data sheet describes the functionality of the CLRC63201T/0FE,112 integrated circuit (IC). It includes functional and electrical specifications and provides details on how to design the device from a system and hardware perspective. CLRC632 is a member of a new family of highly integrated reader ICs for contactless The communication frequency is 13.56 MHz. This family of reader ICs offers:

    1. Excellent modulation and demodulation for passive contactless communication

    2. Extensive methodologies and protocols

    3. Small, fully integrated package

    4. Pin compatibility with MFRC500, MFRC530, MFRC531 and SLRC400 All protocol layers for ISO/IEC 14443 A and ISO/IEC 14443 B communication

Supported standards provide:

    1. Correct use of additional components such as oscillators, power supplies, coils, etc. 

    2. Proper implementation of standardized protocols such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B collision avoidance

The CLRC632 supports contactless communication using MIFARE higher baud rates. The receiver module provides a robust and efficient implementation of demodulation/decoding circuitry compatible with transponder signals. A digital module that manages the full ISO/IEC 14443 standard framework and error detection (parity and CRC). In addition, it supports fast MIFARE security algorithm authentication. The MIFARE product CLRC632 supports all layers of the I-CODE1 and ISO/IEC 15693 protocols. The receiver module provides a robust and efficient demodulation/decoding circuit implementation for I-CODE1 and ISO/IEC 15693 compliant transponder signals. This digital block handles I-CODE1 and ISO/IEC 15693 framing and error detection (CRC). The internal transmitter module can directly drive antennas designed for close-range operation, up to 100mm away, without any additional active circuitry. The parallel interface can be connected directly to any 8-bit microprocessor to ensure flexibility in reader/terminal design. In addition, Serial Peripheral Interface (SPI) compatibility is supported.
