基于PIC单片机的低功耗读卡器硬件设计

Hardware Design of a Low Cost Intelligent Card Reader based on PIC Soc

本文提出了一个完整的基于串口的智能读卡器子系统设计方案并将其实现。读卡器的设计突出了小型化的要求,全部器件使用贴片封装。为了减小读卡器的体积,设计中还使用了串口窃电的技术,使用串口信号线直接给读卡器供电。为此,读卡器使用了省电的设计,采用了省电的集成电路,并大胆简化了许多传统的设计电路。

This paper aims to put forward a complete design of Smart IC card reader based on Serial Port and propose the way of realizing it for the purpose of Network Security. SMD is adopted to make Smart IC reader smaller in this design. To reduce the volume of Smart IC reader, Serial Port powered technology is employed to get power from the signal line of Serial Port. For this reason, low-power consumption components are adopted in the design and some traditional designs are simplified to reduce the power consumption.
