摘　　要：为了降低开发板制作成本,设计一种兼容AT 89S2051,P89LPC917,P89LPC935这三种MCU的单片机开发板,可以根据需要选用其中一种MCU在开发板上进行实验或开发。测试结果证明达到了设计要求。这里就三者的互连与布局、与其他电路和总线接口的布线、功能兼容、占用印制板面积最小等方面做了介绍,并指出这样做遇到的困难和解决的办法。In order to reduce production cost of development board,a single chip computer development board is designed compatibly for three MCUs： AT89S2051 ,P89LPC917 and P89LPC935. One of them can be chosen for experiment or development on this board as needed. The test results prove that meet the design requirments. The interconnection and layout of the three MCUs,wiring to other circuits and bus interface, function compatibility, minimum PCB area occupied and so on, are introduced. The difficulties in doing so and the solutions are also pointed out.
