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 15 for timing waveform, and Fig-
ure 23 and Figure 24 for flowcharts.
Security ID
The SST39VF320xB devices offer a 136 word Security ID space. The Secure ID space is divided into
two segments - one factory programmed segment and one user programmed segment. The first seg-
ment is programmed and locked at SST with a random 128-bit number. The 128-word 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 555H 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.

9. Both Software ID Exit operations are equivalent

using the Sec ID mode again (the programmed “0” bits cannot be reversed to “1”). Valid Word-Addresses for Sec ID are
from 000000H-000007H and 000008H to 000087H.
