Is the use of I2C to write and read data into internal EEPROM of tm4c123gh6pm inevitable?

Hello Ishan,

I2C is not necessary to use internal emulated EEPROM on TM4C which is all accessible through addressable registers on chip. The post you reference is discussing external EEPROM not internal emulated EEPROM. In some cases it is necessary to utilize an external "true" EEPROM chip instead of the provided emulated EEPROM within the device due to limited read/write cycles of the onboard emulated EEPROM within the device. External EEPROMs can have in excess of 1,000,000 write/erase cycles which is well beyond what normal flash can handle.

Note that emulated EEPROM is not truly EEPROM as it is really flash memory that is used for storage by alternating sectors between full and empty sectors. There are many white papers available on the web regarding emulated EEPROM which might come in handy to understand how emulated EEPROM works. The EEPROM section of the user guide covers the use of this module on the TM4C device (as mentioned in another post). the logic of the module takes care of the intricacies of emulated EEPROM behind the scenes (in silicon logic) so that the user can use it in a similar way to real EEPROM. After you have had an opportunity to review, please let us know if there are any questions.
