Deep Power-down (B9h)
Although the standby current during normal operation is relatively low, standby current can be further reduced
with the Deep Power-down instruction. The lower power consumption makes the Deep Power-down
instruction especially useful for battery powered applications (see ICC1 and ICC2 in
Electrical Characteristics on page
instruction code “B9h” as shown in
The CS# pin must be driven high after the eighth bit has been latched. If this is not done the Deep Power-
down instruction will not be executed. After CS# is driven high, the power-down state will entered within the

Release from Deep Power-down / Device ID instruction, which restores the device to normal operation, will
be recognized. All other instructions are ignored. This includes the Read Status Register instruction, which is
always available during normal operation. Ignoring all but one instruction makes the Power Down state a
useful condition for securing maximum write protection. The device always powers-up in the normal operation
with the standby current of ICC1.
