CLRC63201T/0FE

Product Summary

The CL RC632 is member of a new 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 RC 400.
The CL RC632 supports all layers of the ISO14443 including the type A and type B communication scheme.
The CL RC632 supports contactless communication using MIFARE? Higher Baudrates. The receiver part
provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from
ISO14443 compatible transponders.
The digital part handles the complete ISO14443 framing and error detection (Parity & CRC). Additionally it
supports the fast MIFARE? Classic security algorithm to authenticate MIFARE? Classic (e.g. MIFARE?
Standard, MIFARE? Light) products.
The CL RC632 supports all layers of I?CODE1 and ISO 15693. The receiver part provides a robust and
efficient implementation of a demodulation and decoding circuitry for signals from I?CODE1 and ISO 15693
compatible transponders. The digital part handles I?CODE1 and ISO 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 μ-Processor gives high
flexibility for the reader/terminal design.
Additionally a SPI compatible interface is supported.
