Resume from Deep Power-down
AT45DB011D
After initial power-up, the device will default in standby mode. The Deep Power-down command
allows the device to enter into the lowest power consumption mode. To enter the Deep Power-
down mode, the CS pin must first be asserted. Once the CS pin has been asserted, an opcode
of B9H command must be clocked in via input pin (SI). After the last bit of the command has
been clocked in, the CS pin must be de-asserted to initiate the Deep Power-down operation.
After the CS pin is de-asserted, the will device enter the Deep Power-down mode within the
maximum t
are ignored except for the Resume from Deep Power-down command.
Figure 12-1. Deep Power-down
The Resume from Deep Power-down command takes the device out of the Deep Power-down
mode and returns it to the normal standby mode. To Resume from Deep Power-down mode, the
CS pin must first be asserted and an opcode of ABH command must be clocked in via input pin
(SI). After the last bit of the command has been clocked in, the CS pin must be de-asserted to
terminate the Deep Power-down mode. After the CS pin is de-asserted, the device will return to
the normal standby mode within the maximum t
