Data Sheet

Product Identification

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.

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 5 for the software command code, Fig-

ure 17 for timing waveform and Figure 26 for a flowchart.
