MFRC500_cn
MF RC522是应用于13.56MHz非接触式通信中高集成度的读写卡芯片,是NXP公司针对“三表”应用推出的一款低电压、低成本、体积小的非接触式读写卡芯片,是智能仪表和便携式手持设备研发的较好选择。
MF RC522利用了先进的调制和解调概念,完全集成了在13.56MHz下所有类型的被动非接触式通信方式和协议。支持ISO14443A兼容应答器信号。数字部分处理ISO14443A帧和错误检测。此外,还支持快速CRYPTO1加密算法,用语验证MIFARE系列产品。MFRC522支持MIFARE系列更高速的非接触式通信,双向数据传输速率高达424kbit/s。
作为13.56MHz高集成度读写卡系列芯片家族的新成员,MF RC522与MF RC500和MF RC530有不少相似之处,同时也具备许多特点和差异。它与主机间通信采用连线较少的串行通信,且可根据不同的用户需求,选取SPI、IIC或串行UART模式之一,有利于减少连线,缩小PCB板体积,降低成本。 (asdfasdf asdf )

序自从1978年《C程序设计语言》出版以来,计算机界经历了一场革命。大型计算机变得更大;而个人计算机的能力可以和十年前的主流计算机相媲美。在这段时间中,C语言也在悄悄地改变,并且早已超出了仅仅作为UNIX操作系统的语言的范畴。(sequence since 1978 "C Programming Language" has been published, the computer industry has undergone a revolution. Large computers become bigger; But the personal computer and the ability to mainstream a decade ago comparable computer. During this period of time, C language is also quietly change, and already in excess of the UNIX operating system only as the language of the area.)
