contains timing specification tables and timing dia-
grams for write operations.
Program and Erase Operation Status
During an erase or program operation, the system
may check the status of the operation by reading the
status bits on DQ7–DQ0. Standard read cycle timings
and ICC read specifications apply. The Erase Resume
command is valid only during the Erase Suspend
mode.Refer to “Erase Suspend/Erase Resume Com-
mands” on page 17 for more information, and to each
“AC Characteristics” on page 27 section for timing dia-
grams.
Standby Mode
When the system is not reading or writing to the device,
it can place the device in the standby mode. In this
mode, current consumption is greatly reduced, and the
outputs are placed in the high impedance state, inde-
pendent of the OE# input.
The device enters the CMOS standby mode when CE#
and RESET# pins are both held at VCC ± 0.5 V. (Note
that this is a more restricted voltage range than VIH.)
The device enters the TTL standby mode when CE#
and RESET# pins are both held at VIH. The device re-
quires standard access time (tCE) for read access when
the device is in either of these standby modes, before
it is ready to read data.
The device also enters the standby mode when the RE-
SET# pin is driven low. Refer to the next section, “RE-
If the device is deselected during erasure or program-
ming, the device draws active current until the
operation is completed.
ICC3 in DC Characteristics tables, represents the
standby current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of reset-
ting the device to reading array data. When the system
drives the RESET# pin low for at least a period of tRP,
the device immediately terminates any operation in
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 ma-
chine to reading array data. The operation that was in-
terrupted 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 VIL, the device enters
the TTL standby mode; if RESET# is held at VSS ±
0.5 V, the device enters the CMOS standby mode.
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.
If RESET# is asserted during a program or erase oper-
ation, the RY/BY# pin remains a “0” (busy) until the in-
ternal reset operation is complete, which requires a
time of tREADY (during Embedded Algorithms). The sys-
tem 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 tREADY (not during Embedded Algo-
rithms). The system can read data tRH after the RE-
SET# pin returns to VIH.
Refer to the “AC Characteristics” on page 27 tables for
RESET# parameters and timing diagram.
Output Disable Mode
When the OE# input is at VIH, output from the device is
disabled. The output pins are placed in the high imped-
ance state.
