Product Identification
The Product Identification mode identifies the devices as the SST39VF6401B and SST39VF6402B,
and the manufacturer as SST. This mode may be accessed through software operations. Users may
use the Software Product Identification operation to identify the part (i.e., using the device ID) when
using multiple manufacturers in the same socket. For details, see Table 6 for software operation, Figure
11 for the Software ID Entry and Read timing diagram and Figure 21 for the Software ID Entry com-
mand 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 accomplished 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 inad-
vertent transient condition that apparently causes the device to behave abnormally, e.g., not read cor-
rectly. Please note that the Software ID Exit/CFI Exit command is ignored during an internal Program
or Erase operation. See Table 6 for software command codes, Figure 13 for timing waveform, and Fig-
ures 21 and 22 for flowcharts.
