Question

What is the size of EEPROM of the Arduino UNO?

1) 1 KB
2) 2 KB
3) 4 KB
4) 8 KB

Answer 1

The Arduino UNO has an EEPROM size of 1 KB, which is used to store small amounts of data that are retained even when power is lost.

Step-by-step explanation:

The Arduino UNO is equipped with a 1 KB EEPROM (Electrically Erasable Programmable Read-Only Memory), a non-volatile storage solution. This memory is crucial for retaining small but essential data even in the absence of power. The ATmega328P microcontroller, the brain of the Arduino UNO, specifically offers this 1 KB of EEPROM, as outlined in the ATmega328P datasheet. EEPROM allows the Arduino UNO to store and retrieve critical information persistently, making it suitable for applications where data persistence is vital, such as storing configuration settings, calibration values, or other user-defined parameters that need to survive power cycles.
