Design and Implementation of Power Protection Based on Single-chip Microcomputer

Abstract

The protection of instantaneous loss of storage data is an important function of industrial or civil equipment The data of MCU is in RAM memory, therefore data in RAM is unreserveable after losing power. After the power drop, the data in MCU is saved to the EEPROM memory in time. This method is a good solution to the data of MCU after power loss. The principles and methods and procedures are given in this paper.
