Release Deep Power-down / Device ID (ABh)
The Release from Deep Power-down / Device ID command is a multi-purpose command. The device requires
the Release from Deep Power-down command to exit the Deep Power-down mode. When the device is in the
Deep Power-down mode, all commands except Release from Deep Power-down command are ignored. In
addition, the ABh command can also be used to read the device's 8-bit electronic Device ID.
When used only to release the device from the power-down state, the command is issued by driving the CS#
pin low, shifting the command code “ABh” and driving CS# high as shown in Figure 8.13. After the time
duration of t_RES1 (See AC Characteristics on page 31.) the device will resume normal operation and other
commands will be accepted. The CS# pin must remain high during the t_RES1 time duration.
When used only to obtain the Device ID while not in the Deep power-down state, the command is initiated by
driving the CS# pin low and shifting the command code “ABh” followed by 3-dummy bytes. The Device ID bits
are then shifted out on the falling edge of SCK with most significant bit (MSB) first as shown in Figure 8.14.
The Device ID value for the S25FL216K is listed in Manufacturer and Device Identification table. The Device
ID can be read continuously. The command is completed by driving CS# high.
When used to release the device from the Deep power-down state and obtain the Device ID, the command is
the same as previously described, and shown in Figure 8.14, except that after CS# is driven high it must
remain high for a time duration of t_RES2 (See AC Characteristics on page 31.). After this time duration the
device will resume normal operation and other commands will be accepted. If the Release from Deep Power-
down / Device ID command is issued while an Erase, Program or Write cycle is in process (when WIP equals
1) the command is ignored and will not have any effects on the current cycle.
