Data Protection
To protect the data during operation and power on/off, the EEPROMhas the internal functions described below
1. Data Protection against Noise of Control Pins (CE, OE, WE) during Operation.
During readout or standby, noise on the control pins may act as a trigger and turn the EEPROMto programmng mode by ms-
take. To prevent this phenomenon, the EEPROMhas a noise cancellation function that cuts noise if its width is 20ns or less in
programmng mode. Be careful not to allow noise of a width of more than 20ns on the control pins.
2. RES Signal
RES should be kept at V
SS
level when V
CC
is turned on or off. The EEPROMbreaks off programmng operation when RES
become low programmng operation doesnt finish correctly in case that RES falls low during programmng operation. RES
should be kept high for 10 ms after the last data is input
