Data Sheet
Software Data Protection (SDP)
The SST39LF010/020/040 and SST39VF010/020/040 provide the JEDEC approved Software Data
Protection scheme for all data alteration operation, i.e., Program and Erase. Any Program operation
requires the inclusion of a series of three-byte sequence. The three-byte load sequence is used to ini-
tiate the Program operation, providing optimal protection from inadvertent Write operations, e.g., dur-
ing the system power-up or power-down. Any Erase operation requires the inclusion of six-byte load
sequence. These devices are shipped with the Software Data Protection permanently enabled. See
Table 4 for the specific software command codes. During SDP command sequence, invalid commands
will abort the device to read mode, within T RC.
Product Identification
The Product Identification mode identifies the devices as the SST39LF/VF010, SST39LF/VF020, and
SST39LF/VF040 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 opera-
tion, Figure 13 for the Software ID Entry and Read timing diagram, and Figure 19 for the Software ID
entry command sequence flowchart.

Product Identification Mode Exit/Reset
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 operation. Please note that the Software ID Exit command is ignored during an internal Pro-
gram or Erase operation. See Table 4 for software command codes, Figure 14 for timing waveform,
and Figure 19 for a flowchart.
