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
SS
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.
