Description
HN58X25xxx Series is the Serial Peripheral Interface (SPI) EEPROM (Electrically Erasable and
Programmable ROM). It realizes high speed, low power consumption and a high level of reliability by
employing advanced MONOS memory technology and CMOS process and low voltage circuitry technology.
It also has a 64-byte page programming function to make it’s write operation faster.
Note: Hitachi’s serial EEPROM are authorized for using consumer applications such as cellular phones,
