7.6 Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when
addresses remain stable for tACC + 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. ICC5 in the DC Characteristics on page 36 represents the automatic sleep mode current
specification.
7.7 RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading array data. When the system drives the RESET#
pin to VIL 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 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 VSS±0.2 V, the device draws CMOS standby
current (ICC4). If RESET# is held at VIL but not within VSS±0.2 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. Note that the CE# pin should only go to VIL after RESET# has gone to
VIH. Keeping CE# at VIL from power up through the first read could cause the first read to retrieve erroneous data.
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 tREADY (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 tREADY (not during Embedded Algorithms). The system can read data tRH after
the RESET# pin returns to VIH.
Refer to the tables in AC Characteristics on page 38 for RESET# parameters and to Figure 18.2 on page 40 for the timing diagram.
If VID (9.0 V – 11.0 V) is applied to the RESET# pin, the device will enter the Temporary Sector Group Unprotect mode. See
Temporary Sector Group Unprotect on page 18 for more details on this feature.
7.8 Output Disable Mode
When the OE# input is at VIH, output from the device is disabled. The output pins are placed in the high impedance state.
7.9 Autoselect Mode
The autoselect mode provides manufacturer and device identification, sector group protection verification, and Secured Silicon
Sector status through identifier codes output on DQ7–DQ0. This mode is primarily intended for programming equipment to
automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can
also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires VID (9.0 V to 11.0 V) on address pin A9. Address pins A6, A3,
A2, A1, and A0 must be as shown in Table . In addition, when verifying sector group protection, the sector address must appear on
the appropriate highest order address bits (see Table on page 12 and Table on page 14). Table shows the remaining address bits
that are don’t care. When all necessary bits have been set as required, the programming equipment may then read the
corresponding identifier code on DQ7-DQ0.
To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown
in Table on page 28. This method does not require VID. See Command Definitions on page 23 for details on using the autoselect
mode.
