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 32-byte page programming function to make their write operation faster.
Note:
Renesas Technology’s serial EEPROM are authorized for using consumer applications such as
cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Technology’s
sales office before using industrial applications such as automotive systems, embedded controllers,
and meters.
