What is the size of EEPROM on the Arduino UNO?

EEPROM on the Arduino UNO is 1 kilobyte of non-volatile storage built into the ATmega328P microcontroller. This means it retains data after power is removed, unlike RAM. The ATmega328P provides 1 KB of EEPROM, while it also has 32 KB of flash for the program and 2 KB of RAM for runtime data. In code you access EEPROM with the EEPROM library, using addresses from 0 to 1023. So the UNO’s EEPROM size is 1 KB (1024 bytes).
