During an erase or program operation, the system may check
the status of the operation by reading the status bits on
FD7-0 and FD23-16 respectively. Standard read cycle tim-
ings and IFCC read specifications apply. Refer to “Write Op-
eration Status” for more information, and to “Flash AC Char-
acteristics” for timing diagrams.
PROGRAM AND ERASE OPERATION
STATUS
When the system is not reading or writing to the device, it
can place the device in standby mode. In this mode, cur-
rent consump-tion is greatly reduced, and the outputs are
placed in the high impedance state, independent of the
FOE input.
The device enters the CMOS standby mode when the FCS1-
2 and RST pins are held at Vcc ±0.3V. (Note that this is a
more restricted voltage range than VIH.) If FCS
1-2 and RST
are held at VIH, but not within Vcc ± 0.3V the device will
be in the standby mode, but the standby current will be
greater. The device requires standard access time (tCE ) for
read access when the device is in either of these standby
STANDBY 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 au-
tomatic sleep mode is independent of the FCS1-2, FWE,
and FOE 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. IF cc5 in the DC Characteristics table represents
the automatic sleep mode current specification.
AUTOMATIC SLEEP MODE
The RST pin provides a hardware method of resetting the
device to reading array data. When the RST pin is driven
low for at least a period of tRP or greater the device imme-
diately terminates any operation in progress, tristates all out-
put pins, and ignores all read/write commands for the dura-
tion of the RST pulse. The device also resets the internal state
machine to reading array data. The operation that was inter-
rupted should be reinitiated once the device is ready to ac-
cept another command sequence, to ensure data integrity.
Current is reduced for the duration of the RST pulse. When
RST is held at Vss ± 0.3V, the device draws CMOS standby
current (IFCC4). If RST is held at VIL but not within Vss ±
