Product Identification
The Product Identification mode identifies the devices as
the SST39VF1601, SST39VF1602, SST39VF3201, or
SST39VF3202, and manufacturer as SST. This mode
may be accessed 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
6 for software operation, Figure 12 for the Software ID
Entry and Read timing diagram and Figure 22 for the
Software ID Entry command sequence flowchart.
TABLE 3: Product Identification
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 accom-
plished 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 inadvertent transient condition that
apparently causes the device to behave abnormally, e.g.,
not read correctly. Please note that the Software ID Exit/
CFI Exit command is ignored during an internal Program or
Erase operation. See Table 6 for software command
codes, Figure 14 for timing waveform, and Figures 22 and
23 for flowcharts.

Security ID
The SST39VF160x/320x devices offer a 256-bit Security
ID space. The Secure ID space is divided into two 128-bit
segments - one factory programmed segment and one
user programmed segment. The first segment is pro-
grammed and locked at SST with a random 128-bit num-
ber. The user segment is left un-programmed for the
customer to program as desired.
To program the user segment of the Security ID, the user
must use the Security ID Word-Program command. To
detect end-of-write for the SEC ID, read the toggle bits. Do
not use Data# Polling. Once this is complete, the Sec ID
should be locked using the User Sec ID Program Lock-Out.
This disables any future corruption of this space. Note that
regardless of whether or not the Sec ID is locked, neither
Sec ID segment can be erased.
The Secure ID space can be queried by executing a three-
byte command sequence with Enter Sec ID command
(88H) at address 5555H in the last byte sequence. To exit
this mode, the Exit Sec ID command should be executed.
Refer to Table 6 for more details.
