Description

General part information

R1EX24002A Series

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