The Hitachi HN58C256FP17 is a 256Kbit (32K x 8) CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory). EEPROMs are a type of non-volatile memory that can be electrically erased and reprogrammed, offering flexibility in data storage and updates. The 'FP' likely indicates the package type. The '17' is related to the access time, which needs further research to confirm its exact value.
