Data Sheet
Software Data Protection (SDP)
The SST39SF010A/020A/040 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 a
series of three-byte sequence. The three-byte load sequence is used to initiate the Program operation,
providing 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 load sequence. The
SST39SF010A/020A/040 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 device as the SST39SF040, SST39SF010A, or
SST39SF020A and manufacturer as SST. This mode may be accessed by software operations. Users
may wish to 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, Table 4 for software operation,
Figure 12 for the software ID entry and read timing diagram and Figure 18 for the 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 Exit ID command sequence, which returns the device to the Read
operation. Please note that the software reset command is ignored during an internal Program or
Erase operation. See Table 4 for software command codes, Figure 13 for timing waveform and Figure
18 for a flowchart.
