Output Disable Mode
When the system is not reading or writing to the device, it can be placed in to 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# and RESET# pins are both held at V

If the device is deselected during erasure or programming, the device draws active current until the operation

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. Refer to the
Characteristics on page 62
The RESET# pin provides a hardware method of resetting the device to reading array data. When the
RESET# pin is driven low for at least a period of t
progress, output pins go to Hi-Z, and all read/write commands are ignored for the duration of the RESET#
pulse. Program/Erase operations that were 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

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.
