NXP CL RC632


The CL RC632 is member of the Micore I family of highly integrated reader ICs for contactless communication at 13.56 MHz. This reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all kinds of passive contactless communication methods and protocols at 13.56 MHz.

The CL RC632 is pin-compatible to the MF RC500, the MF RC530, the MF RC531 and the SL RC400.

The CL RC632 supports all layers of the ISO/IEC 14443A/B communication scheme, given correct implementation of additional components, like oscillator, power supply, coil etc. and provided that standardised protocols, e.g. like ISO/IEC 14443-4 and/or ISO/IEC 14443 type B anticollision are correctly implemented. The CL RC632 supports contactless communication using MIFAREŽ Higher Baudrates. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO/IEC 14443 compatible transponders. The digital part handles the complete ISO/IEC 14443 framing and error detection (Parity & CRC). Additionally it supports the fast MIFAREŽ Classic security algorithm to authenticate MIFARE Classic (e.g. MIFAREŽ Standard, MIFAREŽ Light) products. The CL RC632 supports all layers of IˇCODE1 and ISO/IEC 15693. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from IˇCODE1 and ISO/IEC 15693 compatible transponders. The digital part handles IˇCODE1 and ISO/IEC 15693 framing and error detection (CRC).

The internal transmitter part is able to drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry. A comfortable parallel interface, which can be directly connected to any 8-bit ľ-Processor gives high flexibility for the reader/terminal design. Additionally a SPI compatible interface is supported.
