概要
説明
The HN58X25128/HN58X25256 Series is the Serial Peripheral Interface compatible (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 the CMOS process and low-voltage circuitry technology. It also has a 64-byte page programming function to make its write operation faster.
