3.3V 1 Megabit (128K x 8-Bit) EEPROM  
When V is turned on or off, noise on the control pins generated by external circuits, such as CPUs, may turn the EEPROM to  
CC  
programming mode by mistake. To prevent this unintentional programming, the EEPROM must be kept in unprogrammable  
state during VCC on/off by using a CPU reset signal to RES pin.  
RES should be kept at V level when VCC is turned on or off. The EEPROM breaks off programming operation when RES  
SS  
become low, programming operation doesnt finish correctly in case that RES falls low during programming operation. RES  
should be kept high for 10 ms after the last data input.  
15ms min  
3. Software Data Protection  
The software data protection function is to prevent unintentional programming 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 EEPROM turns 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.
