2.9

VCC Supply voltage

VCC provides the power supply for all operations (Read, Program and Erase).

The Command Interface is disabled when the VCC Supply voltage is less than the Lockout

voltage, VLKO. This prevents Bus Write Operations from accidentally damaging the data

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 0.1µF capacitor should be connected between the VCC Supply voltage pin and the VSS

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, ICC3.

2.10

VSS Ground

VSS is the reference for all voltage measurements. The device features two VSS pins both of

which must be connected to the system ground.
