Description
R1EX25xxx series is the Serial Peripheral Interface compatible (SPI) EEPROM (Electrically Erasable and
Programmable ROM). They realize 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. They also have a
128-byte page programming function to make their write operation faster.
