Data Sheet  
Product Identification  
Product Identification Mode Exit/  
CFI Mode Exit  
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.  
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.
