摘要
C8051F020是美国Cygnal公司推出的高速、高性能单片机中的代表产品,是完全集成的混合信号系统级芯片(SoC),具有功能全面、应用广泛、性价比高等优点。它具有与8051兼容的CIP-51微控制器内核,指令系统完全相同,熟悉MCS-51系列单片机的工程技术人员可以很容易地掌握C8051F。但两者的内部资源存在较大的差异,不能将8051的程序完全照搬的应用于C8051F单片机中,必须经过一定的处理。介绍了C8051F020单片机与80C51在硬件结构及软件编程时的异同之处,并结合简单例子予以说明。
C8051F020 is one of the representative microchip computers that Cygnal company in USA have nominated with high speed, high performance.It is completely integrated of hybrid signals system on-chip, provided with all-sided function,extensive application and high cost-performance.It has CIP- 51 MCU tiny kernel that can be compatible with 8051＇s, a technical engineer who has been up on MCS-51 series can control C8051F very easily.Owing to both of the internal resources exist big differences, copy as failed. However,CS051F020 can use 8051 program through certain processing. In this paper,the difference on hardware structure and software design is introduced, and the simple example is given.
