Description
HN58X24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable
ROM). They realize high speed, low power consumption and a high level of reliability by employing
advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They also
have a 64-byte page programming function to make their write operation faster.
