Standby Mode
When the system is not reading or writing to the de-
vice, 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, independent of the OE# input.
The device enters the CMOS standby mode when the
CE#f 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#f 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 de-
vice 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.
I
CC3
in the DC Characteristics table represents the
standby current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device en-
ergy consumption. The device automatically enables
this mode when addresses remain stable for t
ACC
+
30 ns. The automatic sleep mode is independent of
the CE#f, WE#, and OE# control signals. Standard ad-
dress access timings provide new data when
addresses are changed. While in sleep mode, output
data is latched and always available to the system.
I
CC4
in the DC Characteristics table represents the
automatic sleep mode current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of re-
setting the device to reading array data. When the
RESET# 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
interrupted should be reinitiated once the device is
ready to accept another command sequence, to en-
sure 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 sys-
tem 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 executing
(RY/BY# pin is “1”), the reset operation is completed
within a time of t
READY
(not during Embedded Algo-
rithms). 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 15 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
impedance state.
