Preliminary Specifications
Software Data Protection (SDP)
The SST39VF3201C/3202C provide the JEDEC approved Software Data Protection scheme for all data
alteration operations, i.e., Program and Erase. Any Program operation requires the inclusion of the
three-byte sequence. The three-byte load sequence is used to initiate the Program operation, provid-
ing optimal protection from inadvertent Write operations, e.g., during the system power-up or power-
down. Any Erase operation requires the inclusion of six-byte sequence. These devices are shipped
with the Software Data Protection permanently enabled. See Table 7 for the specific software com-
mand codes. During SDP command sequence, invalid commands will abort the device to read mode
within T RC. The contents of DQ 15 -DQ 8 can be V IL or V IH , but no other value, during any SDP command
sequence.
Common Flash Memory Interface (CFI)
The SST39VF3201C/3202C also contain the CFI information to describe the characteristics of the
device. In order to enter the CFI Query mode, the system must write the three-byte sequence, same as
product ID entry command with 98H (CFI Query command) to address 555H in the last byte sequence.
The system can also enter the CFI Query mode, by using the one-byte sequence with 55H on Address
and 98H on Data Bus. Once the device enters the CFI Query mode, the system can read CFI data at
the addresses given in Tables 8 through 10. 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 devices as the SST39VF3201Cand SST39VF3202C , 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 7 for software operation, Figure 13
for the Software ID Entry and Read timing diagram and Figure 23 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 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 7 for software command codes, Figure 15 for timing waveform, and Fig-
ure 23 and Figure 24 for flowcharts.
