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 MNOS 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.
Features
• Single supply: 1.8 V to 5.5 V
• Two-wire serial interface (I2C serial bus)
• Clock frequency: 400 kHz
• Power dissipation:
Standby: 2 µA (max)
Active (Read): 1 mA (max)
Active (Write): 5 mA (max)
• Automatic page write: 64-byte/page
• Write cycle time: 5 ms
• Endurance: 106 Cycles
• Data retention: 10 Years
Preliminary: The specifications of this device are subject to change without notice. Please contact your
nearest Renesas Technology’s Sales Dept. regarding specifications.
