Write/Erase Endurance and Data Retention Time
The endurance is 10
(1% cumulative failure rate). The data retention time is more than 10 years when a device is page-
programmed less than 10
Data Protection
To prevent this phenomenon, this device has a noise cancellation function that cuts noise if its width is 20 ns
or less in program mode.

During readout or standby, noise on the control pins may act as a trigger and turn the EEPROM to
programming mode by mistake. Be careful not to allow noise of a width of more than 20 ns on the
control pins.
