1 General description
MFRC630 and MFRC630 plus, the high-performance frontend for MIFARE and NTAG products.
The MFRC630 multi-protocol NFC frontend IC supports the following operating modes:
• Read/write mode supporting ISO/IEC 14443A and MIFARE Classic
• Read/write mode supporting NTAG
The MFRC630’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/
IEC 14443A and MIFARE Cassic 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 MIFARE Classic with 1K memory, MIFARE Classic with 4K memory, MIFARE Ultralight,
MIFARE Ultralight C, MIFARE Plus and MIFARE DESFire products. The MFRC630 supports higher transfer
speeds of the MIFARE product family 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.
In this document the term „MIFARE Classic card“ refers to a MIFARE Classic IC-based contactless card.

2 Features and benefits
• High-performance multi-protocol NFC frontend for transfer speed up to 848 kbit/s
• Supports ISO/IEC 14443 A, MIFARE Classic and NTAG
• Supports MIFARE Classic product encryption by hardware in read/write mode
Allows reading cards based on MIFARE Ultralight, MIFARE Classic with 1 kB memory , MIFARE Classic with
4 kB memory, MIFARE DESFire EV1, MIFARE DESFire EV2 and MIFARE Plus ICs
• Low-power card detection
• Antenna connection with minimum number of external components
• Supported host interfaces:
– SPI up to 10 Mbit/s
– I2C-bus interfaces up to 400 kBd in Fast mode, up to 1000 kBd in Fast mode plus
– RS232 Serial UART up to 1228.8 kBd, with voltage levels dependent on pin voltage supply
• Separate I2C-bus interface for connection of a secure access module (SAM)
• FIFO buffer with size of 512 byte for highest transaction performance
• Flexible and efficient power saving modes including hard power down, standby and low-power card detection
• Cost saving by integrated PLL to derive system clock from 27.12 MHz RF quartz crystal
• 3 V to 5.5 V power supply (MFRC63002)
2.5 V to 5.5 V power supply (MFRC63003)
• Up to 8 free programmable input/output pins
• Typical operating distance in read/write mode for communication to a ISO/IEC 14443A and MIFARE Classic
card up to 12 cm, depending on the antenna size and tuning. The version MFRC63003 offers a more
flexible configuration for Low-Power Card detection compared to the MFRC63002 with the new register
LPCD_OPTIONS. In addition, the MFRC63003 offers new additional settings for the Load Protocol which fit
very well to smaller antennas. The MFRC63003 is therefore the recommended version for new designs.
