Do you means external I2C EEPROM ?
There are several libs out there. There is one already in ESP8266 github :
https://github.com/esp8266/Arduino/tree ... ies/EEPROMHere are 2 other examples where I used one or the other depending of the projects.

Hello,
There is something I don't understand
When you flash an ESP8266-12E (alone) with the sketch : eeprom_clear.ino, where does the sketch write the data?
Is the Program at 00000?
What is the address were are written the data 512 KB?
Thank you.

The emulated EEPROM is located at the end of SPIFFS area, just before the Wifi Config.
