基于MF-RC500的射频卡读写系统设计

Design of the RF card read-write system based on MF-RC500

MF-RC500完整的集成13.56MHz下所有类型的被动非接触式通信方式和协议,是一种先进的集成式射频芯片,本文设计一种基于MF-RC500的射频卡读写系统,系统主控制器采用具有超低功耗特性的MSP430系列微控制器。首先依据系统框图设计硬件电路系统,设计了MSP430f1232与MF-RC500的接口以及天线和EMC回路;另外设计了系统初始化程序及射频卡处理程序。该系统可读写Mifare Pro、Mifare One、Mifare Light等射频卡,具有一定的通用性。

MF-RC500 completely integrates all sorts of passive non-contact communication modes and protocols under the frequency of 13.56MHz, which is an advanced integrated RF chip. This paper presents a RF card read-write system based on MF-RC500.The main controller of system uses MSP430 microcontrollers with ultra-low power consumption. According to the system block diagram we have designed hardware circuit system, the interface of MSP430f123 and MF-RC500, antenna as well as EMC return circuit. Furthermore, we have also designed the programs of initialized system and the RF card processing programs. This system can read and write RF card such as Mifare Pro, Mifare One, Mifare Light, etc., which has a certain generality.
