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 0.1F 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.
2.13
VSS Ground
VSS is the reference for all voltage measurements. The device features two VSS pins which
must be both connected to the system ground.
