Data Sheet
Common Flash Memory Interface (CFI)
The SST39WF800A contains the CFI information that describes the characteristics of the device, and
supports both the original SST CFI Query mode implementation for compatibility with existing SST
devices, as well as the general CFI Query mode.
To enter the SST CFI Query mode, the system must write the three-byte sequence, same as the Prod-
uct ID Entry command, with 98H (CFI Query command) to address 5555H in the last byte sequence.
To enter the general CFI Query mode, the system must write a one-byte sequence using the Entry
command with 98H to address 55H.
Once the device enters the CFI Query mode, the system can read CFI data at the addresses given in
Tables 5 through 7. The system must write the CFI Exit command to return to Read mode from the CFI
Query mode.
Product Identification
The Product Identification mode identifies the device as the SST39WF800B and manufacturer as SST.
This mode is accessed by software operations. Use Software Product Identification operation to iden-
tify 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 12 for the Software ID Entry and Read timing dia-
gram, and Figure 19 for the Software ID Entry command sequence flowchart.

Product Identification Mode Exit/CFI Mode Exit
To return to the standard Read mode, exit the Software Product Identification mode. Issue the Soft-
ware ID Exit command sequence which returns the device to the Read mode.
The Software ID Exit command may also be used to reset the device to the Read mode after any inad-
vertent transient condition that causes the device to behave abnormally, e.g., not read correctly.
The Software ID Exit/CFI Exit command is ignored during an internal Program or Erase operation. See
Table 4 for software command codes, Figure 14 for timing waveform, and Figure 19 for a flowchart.
