说明

恩智浦半导体的 MFRC52202HN1 是 MFRC522 高度集成读写器 IC 的 2.0 版,用于 13.56 MHz 非接触式通信,采用 HVQFN-32 (5x5x0.85mm) 封装。它支持数据速率高达 848 kBd 的 ISO/IEC 14443A/MIFARE 和 NTAG 协议。内部发射器通过 TX1/TX2 输出直接驱动天线,无需额外的有源电路,而接收器则提供强大的解调和解码功能。数字模块可处理完整的 ISO/IEC 14443A 成帧、奇偶校验和 CRC 错误检测。主机接口:SPI(最高 10 Mbit/s)、I2C(最高 400 kHz)和串行 UART。64 字节 FIFO 缓冲器可处理数据传输。功能包括支持 MIFARE Classic 加密、用于安全模块通信的 MFIN/MFOUT、可编程定时器、灵活的中断模式和硬件掉电。电源电压:2.5V 至 3.6V。电流消耗:掉电时为 5uA,激活时典型值为 7mA。工作温度:-25℃ 至 85℃。2.0 版增加了一个额外的定时器预分频器,并修正了 RX Multiple 的 CRC 处理。符合 RoHS 和 EAR99 标准。.

恩智浦半导体的 MFRC52202HN1 是 MFRC522 高度集成读写器 IC 的 2.0 版,用于 13.56 MHz 非接触式通信,采用紧凑型 HVQFN-32 封装(5 x 5 x 0.85 mm,SOT617-1)。该器件是嵌入式系统领域应用最广泛的 RFID 读写器 IC 之一,支持 ISO/IEC 14443A/MIFARE 和 NTAG 协议,用于读写非接触式卡和应答器。.

MFRC52202HN1 在单个芯片中集成了完整的模拟前端 (AFE)、数字协议处理和主机通信接口。内部发射器提供缓冲输出驱动器(TX1、TX2),可直接驱动匹配到 50 欧姆的读写器天线,只需极少的外部元件。接收器模块包括一个强大而高效的执行器,用于解调和解码来自 ISO/IEC 14443A/MIFARE 兼容卡的信号,典型工作距离可达 50 毫米,具体取决于天线设计和调谐。.

数字模块管理完整的 ISO/IEC 14443A 成帧和错误检测(奇偶校验和 CRC)功能,以及 MIFARE Classic 身份验证(MF1xxS20、MF1xxS50、MF1xxS70 在读写模式下采用 CRYPTO1 加密)。64 字节的 FIFO 缓冲器促进了主机与非接触式 UART 之间的高效数据传输。该器件支持三种主机通信接口:SPI(最高 10 Mbit/s)、I2C(最高 400 kHz,可通过 EA 引脚和 D1-D5 编程的 7 位地址)和串行 UART(最高 1.2 Mbit/s),可通过引脚配置进行选择。.

与 1.0 版(MFRC52201HN1)相比,2.0 版的改进包括:提高了在恶劣条件下的稳定性,增加了一个定时器预分频器以实现更灵活的定时配置,以及修正了当 RX Multiple 设置为 1 时的 CRC 处理。.

电源管理功能包括典型电流消耗为 5uA 的硬件掉电模式(通过 NRSTPD 引脚),以及带可编程定时器的软件控制掉电模式,用于自动唤醒。该器件的工作电压为 2.5V 至 3.6V,因此适用于 3.3V 微控制器系统。工作温度范围为 -25C 至 85C。.

后缀 HN1 表示 HVQFN-32 封装,订购代码包括,151 和,157 变体,用于不同的封装选项(卷带式)。该器件符合 RoHS 规范,MSL 1 级,并被归类为 EAR99。.

MFRC52202HN1 可作为 13.56 MHz RFID 读写器运行,执行主机微控制器与非接触式卡或应答器之间的 ISO/IEC 14443A 通信协议的物理层和数据链路层。.

发射机运行:内部发射器使用外部 27.12 MHz 晶体振荡器(连接至 OSCIN/OSCOUT 引脚)和内部 PLL 产生 13.56 MHz 载波频率。载波使用 100% ASK(A 型调制)或在 TxControlReg 寄存器中配置的各种调制深度进行调制。调制载波通过两个推挽输出级(TX1 和 TX2)驱动,这两个输出级通过 LC 匹配网络连接到天线。当 TX1 和 TX2 都启用时(TxControlReg 第 0 位和第 1 位设置),输出以推挽配置驱动天线,以实现最大功率输出。发射机支持 ISO/IEC 14443A 传输速度:106 kBd、212 kBd、424 kBd 和 848 kBd。.

接收器运行:接收器输入端(RX 引脚)从卡的负载调制中捕捉子载波信号。信号通过增益控制放大器,然后通过 I 信道和 Q 信道解调器,利用内部生成的参考信号进行相干检测。解调后的信号由 ADC 进行数字化处理,并由数字相关器进行比特解码。接收器处理完整的 ISO/IEC 14443A 接收链,包括位级成帧、防碰撞协议和碰撞检测。碰撞检测可识别多个卡同时传输不同值的比特位置。.

协议处理:数字模块(非接触式 UART)管理完整的 ISO/IEC 14443A 协议栈:(1) 发送 REQA/WUPA 命令以激活卡片,(2) 从现场多张卡片中选择一张卡片的防冲突序列,(3) 确认卡片选择的 SELECT 命令,(4) MIFARE 身份验证(使用秘钥的 CRYPTO1 相互验证),(5) 具有自动 CRC 生成和验证功能的读/写操作。64 字节 FIFO 缓冲器可存储发送和接收的数据,允许主机读/写大型数据块,而无需满足严格的时间要求。.

主机接口选择:接口模式由 I2C 引脚(引脚 1)和 D1-D7 引脚的状态决定。当 I2C 引脚为高电平时,选择 I2C 接口,7 位从机地址由 EA 引脚和 D1-D5 引脚决定。当 I2C 引脚为低电平时,根据引脚配置选择 SPI 或 UART 模式。在 SPI 模式下,器件使用标准 4 线 SPI(NSS、SCK、MOSI、MISO),NSS 为低电平有效芯片选择。在 UART 模式下,器件使用可配置波特率的串行通信。.

MIFARE 身份验证:MFRC52202HN1 实现了用于 MIFARE Classic 身份验证的 CRYPTO1 流密码。在验证序列中,读卡器发送带有扇区和密钥类型(A 或 B)的验证命令,卡回应一个随机数,然后读卡器和卡进行相互的三次验证。验证成功后,该扇区的所有后续读/写操作都将使用 CRYPTO1 密码进行加密。MFIN 和 MFOUT 引脚允许连接到安全访问模块 (SAM),以加强密钥管理。.

中断系统:IRQ 引脚可为各种事件产生中断,包括:定时器到期、发送结束、接收器 FIFO 满/半满/中断、CRC 错误和碰撞检测。通过中断使能寄存器和状态寄存器,可以对触发中断的事件进行精细控制,从而实现事件驱动编程模型,减少主机处理器轮询开销。.
