Data Sheet
Software Data Protection (SDP)
The SST39WF400B provides the JEDEC approved Software Data Protection scheme for all data alter-
ation 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, providing opti-
mal 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. This group of devices are shipped
with the Software Data Protection permanently enabled. See Table 4 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 SST39WF400B 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 SST39WF400B and the manufacturer as
SST. This mode is accessed by software operations. 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.
