Product Identification
The Product Identification mode identifies the devices as
the SST39VF1681 and SST39VF1682, and manufacturer
as SST. Users may use the software Product Identifica-
tion 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 11
for the software ID Entry and Read timing diagram, and
Figure 21 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 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 13 for timing waveform, and Figures 21 and
22 for flowcharts.
Security ID
The SST39VF168x devices offer a 256-bit Security ID
space which is divided into two 128-bit segments. 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 Byte-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 Security ID space can be queried by executing a
three-byte command sequence with Enter-Sec-ID com-
mand (88H) at address AAAH in the last byte sequence.
Execute the Exit-Sec-ID command to exit this mode. Refer
to Table 6 for more details.
