Note: Each transition
Deep Power-Down
During normal operation, the device will be placed in the standby mode to consume less power as long as the CS pin
remains deasserted and no internal operation is in progress. The Deep Power-Down command offers the ability to place
the device into an even lower power consumption state called the Deep Power-Down mode.
When the device is in the Deep Power-Down mode, all commands including the Read Status Register command will be
ignored with the exception of the Resume from Deep Power-Down command. Since all commands will be ignored, the
mode can be used as an extra protection mechanism against program and erase operations.
Entering the Deep Power-Down mode is accomplished by simply asserting the CS pin, clocking in the opcode of B9h, and
then deasserting the CS pin. Any additional data clocked into the device after the opcode will be ignored. When the CS pin
is deasserted, the device will enter the Deep Power-Down mode within the maximum time of t
The complete opcode must be clocked in before the CS pin is deasserted, and the CS pin must be deasserted on an even
byte boundary (multiples of eight bits); otherwise, the device will abort the operation and return to the standby mode
once the CS pin is deasserted. In addition, the device will default to the standby mode after a power-cycle.
