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 MONOS 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.
