Introduction
This data sheet describes the functionality of the CLRC632 Integrated Circuit (IC). It
includes the functional and electrical specications and from a system and hardware
viewpoint gives detailed information on how to design-in the device.
Remark: The CLRC632 supports all variants of the MIFARE Mini, MIFARE 1K,
MIFARE 4K and MIFARE Ultralight RF identication protocols. To aid readability
throughout this data sheet, the MIFARE Mini, MIFARE 1K, MIFARE 4K and
MIFARE Ultralight products and protocols have the generic name MIFARE.

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 (see
demodulation/decoding circuitry implementation for compatible transponder signals (see
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
