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 128-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.
