vice 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.
See the table in
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
30 ns. The automatic sleep mode is independent of
the CE#, WE#, and OE# control signals. Standard ad-
dress access timings provide new data when ad-
dresses are changed. While in sleep mode, output
data is latched and always available to the system.
Refer to the
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 RE-
SET# pin is driven low for at least a period of t

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. To ensure data integrity,
reinitiate the operation that was interrupted, once the
device is ready to accept another command se-
quence.
Current is reduced for the duration of the RESET#
pulse. When RESET# is held at V
draws CMOS standby current (I

greater.
The RESET# pin can 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.

disabled. The output pins are placed in the high
impedance state.
