Automatic Sleep Mode
RESET#: Hardware Reset Pin
Output Disable Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables
this mode when addresses remain stable for t
CE#, WE#, and OE# control signals. Standard 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

The RESET# pin provides a hardware method of resetting the device to reading array data. When the system
drives the RESET# pin to V
progress, tristates all data output pins, and ignores all read/write attempts for the duration of the RESET#
pulse. The device also resets the internal state machine to reading array data. The operation that was
interrupted 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
draws CMOS standby current (I
current will be greater.
The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firmware from the Flash memory.
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a 0 (busy) until the
internal reset operation is complete, which requires a time of t
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 executing (RY/BY# pin is 1), the reset operation is
completed within a time of t
