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 in program mode.

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