MFRC63102HN,551

• Product Introduction

MFRC631 is a highly integrated transceiver IC that enables contactless communication at 13.56 MHz.

MFRC631 transceiver ICs support the following operating modes:

• 支持ISO/IEC 14443A/MIFARE的读/写模式
• 支持ISO/IEC 14443B的读/写模式

The MFRC631's internal transmitter can drive read/write antennas designed to communicate with ISO/IEC 14443A/MIFARE cards and transmit transponders without the need for additional active circuitry. The digital module manages the full ISO/IEC 14443A framing and error detection functions (parity and parity CRC).

MFRC631 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight, MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. MFRC631 supports high transmission speeds of bidirectional MIFARE up to 848 kbit/s.

MFRC631 supports Layers 2 and 3 of the ISO/IEC 14443B read/write communication scheme, with the exception of conflict prevention. Collision prevention needs to be implemented in the firmware of the host controller as well as in the upper layer.

The following host interfaces are supported:

• 串行外设接口(SPI)
• 串行UART（类似RS232，电压电平取决于针脚电压供应）
• I²C总线接口（已实施两个版本：I2C和I2CL）

MFRC631 supports Secure Access Module (SAM) connectivity. A dedicated stand-alone I2C interface enables SAM connectivity. SAM can be used for high-security key storage and as an extremely high-performance cryptographic coprocessor. A dedicated SAM can be used to connect to MFRC631.
