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
15 ns or less.
Be careful not to allow noise of a width of more than 15 ns on the control pins.

2. Data protection at V
CC
on/off
When V
CC
is turned on or off, noise on the control pins generated by external circuits (CPU, etc) may
act as a trigger and turn the EEPROM to program mode by mistake. To prevent this unintentional
programming, the EEPROM must be kept in an unprogrammable state while the CPU is in an unstable
state.
Note:
The EEPROM should be kept in unprogrammable state during V
CC
on/off by using CPU
RESET signal.
