#eeprom28c64

Read and write operations are dominated by Arduino execution overhead, roughly 120 ns per digital pin operation. Active polling of the EEPROM `READY/BUSY` pin significantly reduces write times, cutting wait from 1400 µs to 600 µs without errors. Sequential write/read tests confirm reliable data transfer, while excessive speed risks corrupting writes. Future work includes testing chip endurance, data retention, and performance across different Arduino clock speeds.

Explored EEPROM 28C64 basics using Arduino. Built a simple API to hide low-level pin control. Verified read/write operations, though some datasheet waveforms don’t match practice. Used breadboard, button, and LCD for control and display. Performance, timing accuracy, and data retention issues remain for future study.
