Data Sheet
by executing a three-byte command sequence with Query
Sec ID command (88H) at address 555H in the last byte
sequence. See Figure 15 for timing diagram. To exit this
mode, the Exit Sec ID command should be executed.
Refer to Table 7 for more details.
Product Identification
The Product Identification mode identifies the devices and
manufacturer. For details, see Table 2 for software opera-
tion, Figure 12 for the Software ID Entry and Read timing
diagram and Figure 22 for the Software ID Entry command
sequence flowchart. The addresses A
bank address. When the addressed bank is switched to
Product Identification mode, it is possible to read another
address from the same bank without issuing a new Soft-
ware ID Entry command. The Software ID Entry command
may be written to an address within a bank that is in Read
Mode or in Erase-Suspend mode. The Software ID Entry
command may not be written while the device is program-
ming or erasing in the other bank.

Product Identification Mode
Exit/CFI Mode Exit
In order to return to the standard Read mode, the Software
Product Identification mode must be exited. Exit is accom-
plished by issuing the Software ID Exit command
sequence, which returns the device to the Read mode. This
command may also be used to reset the device to the Read
mode after any inadvertent transient condition that appar-
ently causes the device to behave abnormally, e.g., not
read correctly. Please note that the Software ID Exit/CFI
Exit command is ignored during an internal Program or
Erase operation. See Table 7 for the software command
code, Figure 14 for timing waveform and Figure 22 for a
flowchart.
