1. Introduction
This document describes the functionality and electrical specifications of the contactless
reader/writer IC MFRC630.
2. General description
The MFRC630 is a highly integrated transceiver IC for contactless communication at
13.56 MHz.
The MFRC630 transceiver IC supports the following operating modes
• Read/write mode supporting ISO/IEC 14443A/MIFARE
The MFRC630’s internal transmitter is able to drive a reader/writer antenna designed to
communicate with ISO/IEC 14443A/MIFARE 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 MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,
MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The MFRC630
supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions.
The following host interfaces are supported:
• Serial Peripheral Interface (SPI)
• Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)
• I²C-bus interface (two versions are implemented: I2C and I2CL)
The MFRC630 supports the connection of a secure access module (SAM). A dedicated
separate I2C interface is implemented for a connection of the SAM. The SAM can be used
for high secure key storage and acts as a very performant crypto coprocessor. A
dedicated SAM is available for connection to the MFRC630.
