Application of serial EEPROM in measuring and cortrol equipment in power system

In this paper,we introduce the application technology of high quality serial EEPROM's measure and control device in electric power system.And the emphas is to introduce the characteristic of 24LCXX system serial EEPROM made in U.S.A.'s Microchip enterprise, and AT88c51 single chip processor's interface circuit and r/w approach. Moreover, we give r/w diagram in detail.
