Not recommended for new designs. For new designs, please use recommended product MFRC630 plus from the CLRC663 plus family.
The MFRC630 is a high-performance frontend supporting the Read/Write mode for ISO/IEC 14443A, MIFARE and NTAG products with a 3 V to 5.5 V power supply. It has a separate I2C-bus interface for the connection of a secure access module (SAM). The MFRC630’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A and MIFARE Classic® IC-based cards and transponders without additional active circuitry. The digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity and CRC). The MFRC630 supports higher transfer speeds of the MIFARE product family of up to 848 kbit/s in both directions.
