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
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 ac-
cept another command sequence, to ensure data in-
tegrity.
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 cur-
rent 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.
Refer to the AC Characteristics tables for RESET# pa-
rameters and to Figure 16 for the timing diagram.
V
CC
Power-up and Power-down Sequencing
The device imposes no restrictions on V
CC
power-up
or power-down sequencing. Asserting RESET# to VIL
is required during the entire V
CC
power sequence until
the respective supplies reach their operating voltages.
Once V
CC
attains its operating voltage, de-assertion of
RESET# to V
IH
is permitted.
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.
