The MFRC630’s internal transmitter is able to drive an antenna for communication with ISO/IEC14443A or MIFARE cards and transponders without additional active circuitry. The device manages the entire ISO/IEC14443A framing and error-detection functionality.
The MFRC630 supports the connection of a Secure Access Module (SAM). A dedicated I2C interface is implemented for connecting the SAM. A SAM can be used for secure key storage.
