摘　　要：集成电路产业沿着摩尔定律高速发展,工艺水平每两年升级换代一次,由此导致了元器件行业的高速发展,也带来了快速的更新换程。然而许多应用要求集成电路要长期稳定工作,不希望元器件更新速度太快以至于提高系统潜在风险,这就与元器件生命周期越来越短形成了矛盾,在单片机方面,由于早期MCS51架构单片机品种众多而且需求量大,此种问题尤其严重。技术上需要利用新的工艺技术,使已有的单片机通过复用扩展,设计出可以同时替代多款单片机的集成电路产品,以满足应用需求。利用L89C51RD2单片机,结合flash可配置的特点,设计了一款单片机产品,可以灵活配置其功能,从而实现对多个系列MCS51架构单片机的替代。With the rapid development of IC industry,according to Moore's Law,the process will upgrade each two years to increase the development of IC chip.But some applications still need stable and long term working rather than the higher upgrade for preventing the system from the potential risks. In Single -Chip -Microcontroller field,this problem is more serious because MCS51 chips have more types and are in great demand.A new process technology is required to introduce a flexible product based on L89C51RD2 microcontroller and some features of flash.It can be configured to replace multi -series microcontroller with MCS51 architecture.
