摘要
针对非接触式13.56M读写器在功耗高、体积大等方面问题,提出了一种低功耗、高安全性的研究模型。模型采用MSP430F2274为主控芯片和MF RC522为射频芯片,在保证通信稳定、抗干扰力强、通信距离能达到10cm的前提下,可以使系统有效降低功耗和体积。经实验,结果表明系统3.3V供电完全适合MF RC522供电要求,实现了低功耗的完美结合。
According to contaetless reader of 13.56MHz in power and volume problems, the paper puts forward a low-power high security research model.The model used MSP430F2272 for control chip and RC522 for RF chip, In order to ensure stable and anti-interference ability, communication distance can achieve 10mm premise, can make the system effectively reduce power consumption and volume. The experiment results show that the system, power supply suitable for 3.3V MF RC522 power requirements, realizes the perfect combination of low power consumption.
