| Abstract: | The I^2C bus is a serial communication bus, which has been developed in recent years in the microcontroller area. Its applicable areas are more and more due to its many advantages. The features of I^2C EEPROM 24LC32 were described simply in this paper, the bus characteristics and operation rules of I^2C EEPROM 24LC32 were narrated in detail, including the selection of 24LC32 device on the I^2C-bus, random read and current read, byte write and page write. The interface circuit between 24LC32 and 80C196 was presented, and it has been applied in the intelligent thermal relay. |
