EOL Data Sheet
Product Identification
The Product Identification mode identifies the device as
SST39LF080 or SST39VF080 and manufacturer as SST.
This mode may be accessed by software operations.
Users may use the Software Product Identification opera-
tion to identify the part (i.e., using the device ID) when using
multiple manufacturers in the same socket. For details, see
ID Entry and Read timing diagram and Figure 18 for the
Software ID Entry command sequence flowchart.

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 operation.
This command may also be used to reset the device to the
Read mode after any inadvertent transient condition that
apparently 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 4 for software command
codes, Figure 13 for timing waveform and Figure 18 for a
flowchart.
