EEPROM 28C64 API Performance with Arduino
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.
