Pin Operation
During a write cycle, addresses are latched by the falling edge of
WE
or
CE
, and data is latched by the rising
edge of
WE
or
CE
.
Write/Erase Endurance and Data Retention Time
The endurance is 10
5
cycles in case of the page programming and 10
4
cycles in case of the byte programming
(1% cumulative failure rate). The data retention time is more than 10 years when a device is page-
programmed less than 10
4
cycles.
Data Protection
1. Data Protection against Noise on Control Pins (
CE
,
OE
,
WE
) during Operation
During readout or standby, noise on the control pins may act as a trigger and turn the EEPROM to
programming mode by mistake.
To prevent this phenomenon, this device has a noise cancelation function that cuts noise if its width is 20 ns
or less.
Be careful not to allow noise of a width of more than 20 ns on the control pins.
