Performance

An Arduino-based EEPROM Programmer supporting AT28C devices is evaluated, highlighting wiring, performance, and hardware constraints. Advanced features like RDY/BUSY polling and page-write mode enable major speedups on DUE but are not viable on MEGA.

Page-write support in the AT28C256 can significantly speed up programming, but it depends on tight timing. The Arduino Mega is too slow to use this feature reliably, while faster platforms like the Arduino Due make it practical and stable.

Oscilloscope measurements quantify the execution time of a simple digital pin toggle across multiple Arduino boards. Results show that faster CPUs complete the operation in fewer microseconds, though instruction overhead varies by architecture. The data confirm a near-linear relationship between CPU clock speed and pin toggle performance.

Evaluation of EEPROM Programmer performance on Arduino. Overhead from digital I/O measured, and oscilloscope traces confirmed datasheet timing. Active polling of the READY/BUSY pin reduced write latency while maintaining reliability. Sequential write/read verification showed consistent integrity. Future work includes endurance testing, retention studies, and comparing Arduino boards with different clock speeds.
