Fast Bulk Erase mode
The Fast Bulk Erase mode is used to speed up Bulk Erase operations. The device enters
the Fast Bulk Erase mode during a Bulk Erase instruction whenever a voltage equal to V
PPH
is applied to the W/V pin.

The use of the Fast Bulk Erase mode requires specific operating conditions in addition to the
normal ones (V must be within the normal operating range):

the cumulated time during which W/V is at V
should be less than 80 hours.

Active Power, Standby Power and Deep Power-down modes
When Chip Select (S) is Low, the device is selected, and in the Active Power mode.
When Chip Select (S) is High, the device is deselected, but could remain in the Active Power
mode until all internal cycles have completed (Program, Erase, Write Status Register). The
device then goes in to the Standby Power mode. The device consumption drops to I
.
CC1
The Deep Power-down mode is entered when the specific instruction (the Deep Power-
down (DP) instruction) is executed. The device consumption drops further to I . The
CC2
device remains in this mode until another specific instruction (the Release from Deep
Power-down (RDP) instruction) is executed.
While in the Deep Power-down mode, the device ignores all Write, Program and Erase
instructions (see Deep Power-down (DP)), this can be used as an extra software protection
mechanism, when the device is not in active use, to protect the device from inadvertent
Write, Program or Erase instructions.
4.7
Status Register
The Status Register contains a number of status and control bits that can be read or set (as
appropriate) by specific instructions. See Section 6.4: Read Status Register (RDSR) for a
detailed description of the Status Register bits.
