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 32-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): 3.5 mA (max)
Automatic page write: 32-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.

Write Operations
Byte Write:
A write operation requires an 8-bit device address word with R/W = “0”. Then the EEPROM sends
acknowledgment "0" at the ninth clock cycle. After these, the 64kbit EEPROM receives 2 sequence 8-bit
memory address words. Upon receipt of this memory address, the EEPROM outputs acknowledgment "0"
and receives a following 8-bit write data. After receipt of write data, the EEPROM outputs
acknowledgment "0". If the EEPROM receives a stop condition, the EEPROM enters an internally-timed
write cycle and terminates receipt of SCL, SDA inputs until completion of the write cycle. The EEPROM
returns to a standby mode after completion of the write cycle.
