POWER-UP AND POWER-DOWN
At Power-up and Power-down, the device must
not be selected (that is Chip Select (S) must follow
the voltage applied on V
CC
) until V
CC
reaches the
correct value:
–
V
CC
(min) at Power-up, and then for a further
delay of t
VSL
–
V
SS
at Power-down
Usually a simple pull-up resistor on Chip Select (S)
can be used to insure safe and proper Power-up
and Power-down.
To avoid data corruption and inadvertent write op-
erations during power up, a Power On Reset
(POR) circuit is included. The logic inside the de-
vice is held reset while V
CC
is less than the POR
threshold value, V
WI
– all operations are disabled,
and the device does not respond to any instruc-
tion.
Moreover, the device ignores all Write Enable
(WREN), Page Program (PP), Sector Erase (SE),
Bulk Erase (BE) and Write Status Register
(WRSR) instructions until a time delay of t
PUW
has
elapsed after the moment that V
CC
rises above the
V
WI
threshold. However, the correct operation of
the device is not guaranteed if, by this time, V
CC
is
still below V
CC
(min). No Write Status Register,
Program or Erase instructions should be sent until
the later of:
–
t
PUW
after V
CC
passed the V
WI
threshold
–
t
VSL
afterV
CC
passed the V
CC
(min) level
These values are specified in
Table 7.
.
If the delay, t
VSL
, has elapsed, after V
CC
has risen
above V
CC
(min), the device can be selected for
READ instructions even if the t
PUW
delay is not yet
fully elapsed.
At Power-up, the device is in the following state:
–
The device is in the Standby mode (not the
Deep Power-down mode).
–
The Write Enable Latch (WEL) bit is reset.
Normal precautions must be taken for supply rail
decoupling, to stabilize the V
CC
feed. Each device
in a system should have the V
CC
rail decoupled by
a suitable capacitor close to the package pins.
(Generally, this capacitor is of the order of 0.1μF).
At Power-down, when V
CC
drops from the operat-
ing voltage, to below the POR threshold value,
V
WI
, all operations are disabled and the device
does not respond to any instruction. (The designer
needs to be aware that if a Power-down occurs
while a Write, Program or Erase cycle is in
progress, some data corruption can result.)
