The MF RC530 supports all layers of the ISO14443A communication scheme.

The MF RC530 supports contactless communication using MIFARE® Higher Baudrates.

The internal transmitter part is able to drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry.

The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO14443A compatible transponders.

The digital part handles the complete ISO14443A 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.

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.
