9-25. Deep Power-down (DP)

The Deep Power-down (DP) instruction is for setting the device to minimum power consumption (the standby

current is reduced from ISB1 to ISB2). The Deep Power-down mode requires the Deep Power-down (DP) instruction

to enter, during the Deep Power-down mode, the device is not active and all Write/Program/Erase instruction are

ignored. When CS# goes high, the device is in deep power-down mode, not standby mode.

The sequence of issuing DP instruction is: CS# goes low→sending DP instruction code→CS# goes high.

The SIO[3:1] are "don't care".

Once the DP instruction is set, all instructions will be ignored except CS# toggling for tRDP timing as "Figure 32.

Release from Deep Power-down (RDP) Sequence". When Power-down, or software reset command the deep

power-down mode automatically stops, and when power-up, the device automatically is in standby mode. For

DP instruction the CS# must go high exactly at the byte boundary (the latest eighth bit of instruction code been

latched-in); otherwise, the instruction will not be executed. As soon as Chip Select (CS#) goes high, a delay of tDP

is required before entering the Deep Power-down mode. In addition, a Deep Power Down Delay time (tDPDD) is

required before release from deep power down once entering deep power down mode.
