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 soft-
ware operation, Figure 12 for the Software ID Entry and Read timing diagram and Figure 22 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 6 for software command codes, Figure 14 for timing waveform, and Fig-
ures 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 programmed and locked at SST with a random 128-bit number. 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 com-
mand should be executed. Refer to Table 6 for more details.
