R1EX24256BSAS0A Datasheet | Renesas

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. Note: Renesas Electronics’ serial EEPROM are authorized for using consumer applications such as cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Electronics’ sales office before using industrial applications such as automotive systems, embedded controllers, and meters.
