用单片机，有些数据设置后需要掉电不丢失，一般首先想到的是使用eeprom，比如AVR中的Atmega系列有内部eeprom，也可以外接AT24C01之类的eeprom。这里介绍另外一种参数保存方法，Silicon Laboratories的C8051F系列，其内部程序存储区Flash可以在系统编程，功能类似于eeprom，掉电不丢失。
C8051F310内部有16K的在系统可编程Flash，地址从0x0000到0x3dff，以512字节作为一个扇区，这意味着每次擦除的时候，是对整个扇区擦除（置1），它不是面向单字节操作的，这点与eeprom不同。
-MCU, some of the data set is required after power failure, generally the first thought is to use the eeprom, such as AVR Atmega series of internal eeprom, you can add AT24C01 like eeprom. Here is another parameter preservation methods, Silicon Laboratories of C8051F series, its internal Flash program memory can be programmed in-system, similar in function eeprom, power failure. C8051F310 internal 16K in-system programmable Flash, address from 0x0000 to 0x3dff, as a 512-byte sectors, which means that each erasure, it is for the entire sector erase (set to 1), it is not single byte-oriented operations, and this point and eeprom different.
