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
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
