Deep Power-down (DP)
Executing the Deep Power-down (DP) instruction
is the only way to put the device in the lowest con-
sumption mode (the Deep Power-down mode). It
can also be used as an extra software protection
mechanism, while the device is not in active use,
since in this mode, the device ignores all Write,
Program and Erase instructions.
Driving Chip Select (S) High deselects the device,
and puts the device in Standby Power mode (if
there is no internal cycle currently in progress). But
this mode is not the Deep Power-down mode. The
Deep Power-down mode can only be entered by
executing the Deep Power-down (DP) instruction,
subsequently reducing the standby current (from
I
CC1
to I
CC2
, as specified in
Table 12.
).
Once the device has entered the Deep Power-
down mode, all instructions are ignored except the
Release from Deep Power-down (RDP) instruc-
tion. This releases the device from this mode.
The Deep Power-down mode automatically stops
at Power-down, and the device always Powers-up
in Standby Power mode.
The Deep Power-down (DP) instruction is entered
by driving Chip Select (S) Low, followed by the in-
struction code on Serial Data Input (D). Chip Se-
lect (S) must be driven Low for the entire duration
of the sequence.
The instruction sequence is shown in
Figure 18.
Chip Select (S) must be driven High after the
eighth bit of the instruction code has been latched
in, otherwise the Deep Power-down (DP) instruc-
tion is not executed. As soon as Chip Select (S) is
driven High, it requires a delay of t
DP
before the
supply current is reduced to I
CC2
and the Deep
Power-down mode is entered.
Any Deep Power-down (DP) instruction, while an
Erase, Program or Write cycle is in progress, is re-
jected without having any effects on the cycle that
is in progress.
