Standby Mode
When the system is not reading or writing to the device,
it can place the device in the standby mode. In this
mode, current consumption is greatly reduced, and the
outputs are placed in the high impedance state, inde-
pendent of the OE# input.
The device enters the CMOS standby mode when the
CE# and RESET# pins are both held at V
CC
±
0.3 V.
(Note that this is a more restricted voltage range than
V
IH
.) If CE# and RESET# are held at V
IH
, but not within
V
CC
±
0.3 V, the device will be in the standby mode, but
the standby current will be greater. The device requires
standard access time (t
CE
) for read access when the
device is in either of these standby modes, before it is
ready to read data.
If the device is deselected during erasure or program-
ming, the device draws active current until the
operation is completed.
In the DC Characteristics tables, I
CC3
and I
CC4
repre-
sents the standby current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device
energy consumption. The device automatically
enables this mode when addresses remain stable for
t
ACC
+ 30 ns. The automatic sleep mode is indepen-
dent of the CE#, WE#, and OE# control signals. Stan-
dard address access timings provide new data when
addresses are changed. While in sleep mode, output
data is latched and always available to the system. I
CC5
in the DC Characteristics table represents the auto-
matic sleep mode current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of reset-
ting the device to reading array data. When the RE-
SET# pin is driven low for at least a period of t
RP
, the
device
immediately terminates
any operation in
progress, tristates all output pins, and ignores all
read/write commands for the duration of the RESET#
pulse. The device also resets the internal state ma-
chine to reading array data. The operation that was in-
terrupted should be reinitiated once the device is ready
to accept another command sequence, to ensure data
integrity.
Current is reduced for the duration of the RESET#
pulse. When RESET# is held at V
SS
±0.3 V, the device
draws CMOS standby current (I
CC4
). If RESET# is held
at V
IL
but not within V
SS
±0.3 V, the standby current will
be greater.
The RESET# pin may be tied to the system reset cir-
cuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firm-
ware from the Flash memory.
If RESET# is asserted during a program or erase op-
eration, the RY/BY# pin remains a “0” (busy) until the
internal reset operation is complete, which requires a
time of t
READY
(during Embedded Algorithms). The
system can thus monitor RY/BY# to determine
whether the reset operation is complete. If RESET# is
asserted when a program or erase operation is not ex-
ecuting (RY/BY# pin is “1”), the reset operation is
completed within a time of t
READY
(not during Embed-
ded Algorithms). The system can read data t
RH
after
the RESET# pin returns to V
IH
.
Refer to the AC Characteristics tables for RESET# pa-
rameters and to Figure 13 for the timing diagram.
Output Disable Mode
When the OE# input is at V
IH
, output from the device is
disabled. The output pins are placed in the high imped-
ance state.
