28LV011
05.28.02 Rev 2
When V
CC
is turned on or off, noise on the control pins generated by external circuits, such as CPUs, may turn the EEPROMto
programmng mode by mstake. To prevent this unintentional programmng, the EEPROMmust be kept in unprogrammable
state during V
CC
on/off by using a CPU reset signal to RES pin.
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 input.
3. Software Data Protection
The software data protection function is to prevent unintentional programmng caused by noise generated by external circuits.
In software data protection mode, 3 bytes of data must be input before write data as follows. These bytes can switch the non-
protection mode to the protection mode.
Software data protection mode can be canceled by inputting the following 6 bytes. Then, the EEPROMturns to the non-protec-
tion mode and can write data normally. However, when the data is input in the canceling cycle, the data cannot be written.
