STC单片机大部分内部集成了EEPROM，也有部分单片机没有专门的EEPROM，但可以将用户程序区存储用户程序后剩余的Flash当EEPROM使用，如IAP15W4K61S4,IRC15W4K63S4。EEPROM擦写次数在10万次以上。EEPROM擦写是按扇区擦写的，需要一次擦写的数据尽量放在同一扇区。停电时EEPROM不会丢失数据，可用以保存一些设置参数，或在停电关机前保存本次运行的部分参数，供下次运行时使用。与IAP及EEPROM相关的寄存器如下：
下面寄存器的说明：
下面我们来写ISP/IAP操作的库函数。新建两个文件，分别以stceeprom.h,stceeprom.c存入C51 Template文件夹下Library文件夹中。完成后的头文件如下:
