IC卡读写电路的设计及编程

摘    要
接触式IC卡具有结构简单、成本低廉等优点，因此在我们的生活中还有着非常广泛的应用。本系统就以德国SIMENS(西门子)公司设计的逻辑加密存储卡SLE4442作为主要研究对象，然后围绕其应用中的周边电路及设备进行讨论。从硬件和软件两个方面来对系统分别进行设计，最后再对系统的软硬件进行优化，以实现软硬件的完美结合。完成其功能要求。
首先，本文对IC卡的由来、发展历史、现状以及未来的发展方向进行了简要的介绍。
其次，本文叙述了单片机系统的基本组成以及其工作原理，并介绍了由单片机构成的系统的优点。
再次，讨论了接触式IC卡读写电路实现的基本方法，分析了它的工作原理，并且给出了其实现的具体电路以及IC卡读写电路的软件设计方法。
最后，在附录中，本文还将给出一些必要的系统设计资料，供参考之用。

The IC card reads and writes design and programming of the circuit

Abstract
The contact-type IC card has advantage of simple structure, and the cost is cheap, so there is very extensive application in our life. This system encrypts the storage card SLE4442 as the main research object with the logic that Germany SIMENS Company designs, then organize discussion around peripheral circuit and apparatus in its application. Design the system respectively from hardware and software two respects, optimize the software and hardware of the system afterwards, in order to realize the perfect combination of the software and hardware. Finish its function's requiring.
First of all, this text has introduced the brief one to the origin, developing history, current situation and future developing direction of the IC card.
Secondly, this text has narrated basic composition of the one-chip computer system and its operation principle, have introduced the advantage of the system become by the single organization.
Moreover, it is discussed that the contact-type IC card reads and writes the basic tool that the circuit realizes, has analyzed its operation principle, and concrete circuit and IC card providing its realization read and write the software design method of the circuit.
Finally, in the appendix, this text will also provide some essential systems and design the materials, for reference.

Key words: IC card, One-chip computer, The radio frequency IC card, Reading and writing device
