Description
R1EX24xxx 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 16-byte page programming function to make their write operation faster.
