The MFRC630 is a highly integrated oneTransceiver ICsfor contactless communication at 13.56 MHz.
The MFRC630 transceiver IC supports the following modes of operation:
- Supports read/write mode of ISO/IEC 14443A/MIFARE
The MFRC630's internal transmitter requires no additional active circuitry to drive a read/write antenna designed for communication with ISO/IEC 14443A/MIFARE cards and transmit transponders. The digital module manages the full ISO/IEC 14443A framing and error detection functions (parity and CRC).
The MFRC630 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight, MIFARE Ultralight C, MIFARE PLUS, and MIFARE DESFire products. The MFRC630 supports bidirectional MIFARE speeds of up to 848 kbit/s.
The following host interfaces are supported:
- Serial Peripheral Interface (SPI)
- Serial UART (similar to RS232, voltage level depends on pin voltage supply)
- I²C-bus interface (two versions implemented: I2C and I2CL)
The MFRC630 supports Secure Access Module (SAM) connectivity. A dedicated stand-alone I2C interface implements SAM connectivity. SAM can be used for highly secure key storage and as a very high-performance cryptographic coprocessor. A dedicated SAM can be used to connect to the MFRC630.
