VCC supply voltage  
The V supply voltage supplies the power for all operations (Read, Program, Erase etc.).  
CC  
The command interface is disabled when the V supply voltage is less than the lockout  
CC  
voltage, V  
. This prevents Bus Write operations from accidentally damaging the data  
LKO  
during power-up, power-down and power surges. If the Program/Erase controller is  
programming or erasing during this time then the operation aborts and the memory contents  
being altered will be invalid.  
A 0.1 µF capacitor should be connected between the V supply voltage pin and the V  
CC

ground pin to decouple the current surges from the power supply. The PCB track widths  
must be sufficient to carry the currents required during program and erase operations, I

VSS ground  
The V ground is the reference for all voltage measurements.
