first of all you should know the I2C protocol
specifically which controller you are using in 8051?

check that controller does it contain I2C module or not

if not you need to develop I2C driver for the controller

Hi friend

You don't give eeprom IC no.
If it is AT24c02 then read datasheet of AT24c02.

this give all required step to read and write with at24c02.
and for this eeprom, does not require any I2C module.

only write code, and eeprom work with any type of Microcontroller.

Hope this is help you.
