POWER CONSUMPTION
Power Down
The memory provides Reset/Power Down control
input RPF. The Power Down function can be acti-
vated only if the relevant Configuration Register bit
is set to '1'. In this case, when the RPF signal is
pulled at VSS the supply current drops to typically
IDDD (see Table 24), the memory is deselected
and the outputs are in high impedance.If RPF is
pulled to VSS during a Program or Erase opera-
tion, this operation is aborted in tPLQ7V and the
memory content is no longer valid (see Reset/
Power Down input description).
Power Up
The memory Command Interface is reset on Pow-
er Up to Read Array. Either EF or WF must be tied
to VIH during Power Up to allow maximum security
and the possibility to write a command on the first
rising edge of WF.
Supply Rails
Normal precautions must be taken for supply volt-
age decoupling; each device in a system should
have the VCCF rails decoupled with a 0.1µF capac-
itor closetothe VCCF and VSS pins. The PCB trace
widths should be sufficient to carry the required
VCCF program and erase currents.
