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.

(1) Protection by
RES
The unprogrammable state can be realized by that the CPU’s reset signal inputs directly to the EEPROM’s
RES
pin.
RES
should be kept V
SS
level during V
CC
on/off.
The EEPROM brakes off programming operation when
RES
becomes low, programming operation doesn’t
finish correctly in case that
RES
falls low during programming operation.
RES
should be kept high for 15
ms after the last data input.
