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 cancellation 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.
