MFRC63102HN,151

The MFRC631 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. The MFRC631 transceiver IC supports the following operating modes

Read/write mode supporting ISO/IEC 14443A/MIFARE Read/write mode supporting ISO/IEC 14443B.

The MFRC631’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 MFRC631 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight, MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The MFRC631 supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions. The MFRC631 supports layer 2 and 3 of the ISO/IEC 14443B reader/writer communication scheme except anticollision. The anticollision needs to be implemented in the firmware of the host controller as well as in the upper layers. 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 MFRC631 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 MFRC631.
