Finally, the device is disabled, until RP# is brought
to V
This provides an additional level of protection.

When designing portable systems, designers must
consider battery power consumption not only during
device operation, but also for data retention during
system idle time. Flash nonvolatility increases
usable battery life because the 28F001BX does not
consume any power to retain code or data when the
system is off.

28F001BX Power Dissipation
In addition, the 28F001BX’s deep power-down
mode ensures extremely low power dissipation
even when system power is applied. For example,
laptop and other PC applications, after copying
BIOS to DRAM, can lower RP# to V
negligible power consumption. If access to the boot
code is again needed, as in case of a system
RESET#, the part can again be accessed, following
the t
raised back to V
the device while in power-down requires time t
after RP# transitions high, before outputs are valid.
Further accesses follow normal timing. See AC
