Abstract

Along with the quick development of electronic technology, the technology of All wriable card design has got great raising ,has gotten quick development
Graduate the program of design is "the design sle4442 All wriable card ", carry out its realization and the design of signal generator mainly with the Atmel company's only flat machine of 5l and Max232 for key parts as well as other peripheral circuit and its corresponding interface. To complete the multi-function signal output; and it can realize microprocessor interface circuits between the All wriable card and SCM through the external circuits; and it can make C51 programme prepared MCU to control the interface programme of the external signal chip to realize the output function Of MCU;and it can carry out the long-distance data transmission through RS232 interface with the computer communications。
This paper elaborated sle4442 logic encryption Card Reader cards for the principle, the hardware design and software design; given circuit diagram and control procedures.

Keywords: MPU；sle4442；All writable card
