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.
Note: Hitachi’s serial EEPROM are authorized for using consumer applications such as cellular phone,
camcorders, audio equipment. Therefore, please contact Hitachi’s sales office before using
industrial applications such as automotive systems, embedded controllers, and meters.
