Write/Erase Endurance and Data Retention Time
The endurance is 10
programming (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 15
ns or less.
1. Data Protection against Noise on Control Pins (
Rev.3.00, Feb.02.2004, page 20 of 26
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 15 ns on the
control pins.
