Data Sheet
Product Identification
Product Identification Mode
Exit/CFI Mode Exit
The Product Identification mode identifies the devices and
manufacturer. For details, see Table 2 for software opera-
tion, Figure 15 for the Software ID Entry and Read timing
diagram and Figure 25 for the Software ID Entry command
sequence flowchart. The addresses A19 and A18 indicate 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.
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 5 for the software command code, Fig-
ure 17 for timing waveform and Figure 26 for a flowchart.
