CLRC632 Multiple protocol contactless reader IC (MIFARE/I-CODE1) Rev. 3.5 10 November 2009 Product data sheet 073935 PUBLIC 1. 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. 2. 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 Section 9.12 on page 40). The receiver module provides a robust and efcient demodulation/decoding circuitry implementation for compatible transponder signals (see Section 9.10 on page 34). 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 (see Section 9.14 on page 42).CLRC632 NXP Semiconductors Multiple protocol contactless reader IC (MIFARE/I-CODE1) All layers of the I-CODE1 and ISO/IEC 15693 protocols are supported by the CLRC632. The receiver module provides a robust and efcient 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 exibility. In addition, Serial Peripheral Interface (SPI) compatibility is supported (see Section 9.1.4 on page 9). 3.
