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.
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. Be careful not to allow noise of a width of more than 20 ns on the control pins.
