Data Sheet
Product Identification
The Product Identification mode identifies the devices as
the SST39LF/VF200A, SST39LF/VF400A and SST39LF/
VF800A and manufacturer as SST. This mode may be
accessed by 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 4
for software operation, Figure 13 for the Software ID Entry
and Read timing diagram, and Figure 20 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 mode.
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 15 for timing waveform, and Figure 20 for a
flowchart.
