自从我95年接触PIC单片机以来，便一直热衷于这种单片机的开发与应用。有不少朋友问我：PIC到底有什么优势？也许你也会有这样的疑问，所以我在这里略谈几点自己的看法。
1)PIC大的特点是不搞单纯的功能堆积，而是从实际出发，重视产品的性能与价格比，靠发展多种型号来满足不同层次的应用要求。就实际而言，不同的应用对单片机功能和资源的需求也是不同的。比如，一个摩托车的点火器需要一个I/O较少、RAM及程序存储空间不大、可靠性较高的小型单片机，若采用40脚且功能强大的单片机，投资大不说，使用起来也不方便。PIC系列从低到高有几十个型号，可以满足各种需要。其中，PIC12C508单片机仅有8个引脚，是世界上小的单片机。
该型号有512字节ROM、25字节RAM、一个8位定时器、一根输入线、5根I/O线，市面售价在3－6元人人民币。这样一款单片机在象摩托车点火器这样的应用无疑是非常适合。PIC的型号，如PIC16C74（尚不是型号）有40个引脚，其内部资源为ROM共4K、192字节RAM、8路A/D、3个8位定时器、2个*模块、三个串行口、1个并行口、11个中断源、33个I/O脚。这样一个型号可以和其它的型号媲美。
