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 independent of the 
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. Note that during 
automatic sleep mode, OE# must be at V
IH
 before the device reduces current to the stated sleep mode 
specification. ICC5 in 
DC Characteristics
  on page 71
 represents the automatic sleep mode current 
specification.

RESET#: Hardware Reset Pin
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
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 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
SS
±0.3 V, the device 
draws CMOS standby current (ICC4). 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 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
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 executing (RY/BY# pin is “1”), the reset operation is 
completed within a time of t
READY
 (not during Embedded Algorithms). The system can read data t
RH
 after the 
RESET# pin returns to V
IH
.
Refer to the tables in 
AC Characteristic
  on page 72
 for RESET# parameters and to 
Figure 20.5  on page 75
for the timing diagram.
10.7
Output Disable Mode
When the OE# input is at V
IH
, output from the device is disabled. The output pins (except for RY/BY#) are 
placed in the highest Impedance state
