Description
The R1EX24256B is a two-wire serial interface 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.
