Product Identification
The Product Identification mode identifies the devices as
the SST38VF6401, SST38VF6402, SST38VF6403, or
SST38VF6404, and the manufacturer as SST. See Table 3
for specific address and data information. Product Identifi-
cation mode is accessed through software operations. The
software Product Identification operations identify the part,
and can be useful when using multiple manufacturers in
the same socket. For details, see Table 11 for software
operation, Figure 16 for the software ID Entry and Read
timing diagram, and Figure 27 for the software ID Entry
command sequence flowchart.
TABLE 3: Product Identification
While in Product Identification mode, the Read Block Pro-
tection Status command determines if a block is pro-
tected. The status returned indicates if the block has been
protected, but does not differentiate between Volatile
Block Protection and Non-Volatile Block Protection. See
Table 11 for further details.
The Read-Irreversible Block-Lock Status command indi-
cates if the Irreversible Block Command has been issued.
If DQ
previously issued.
In order to return to the standard Read mode, the software
Product Identification mode must be exited. The exit is
accomplished by issuing the software ID Exit command
sequence, which returns the device to the Read mode.
See Table 11 for software command codes, Figure 18 for
timing waveform, and Figures 27 and 28 for flowcharts.

Security ID
The SST38VF6401/6402/6403/6404 devices offer a Secu-
rity ID feature. The Secure ID space is divided into two seg-
ments — one factory programmed 128 bit segment and
one user programmable 256 word segment. See Table 4
for address information. The first segment is programmed
and locked at SST and contains a 128 bit Unique ID which
uniquely identifies the device. The user segment is left un-
programmed for the customer to program as desired.
TABLE 4: Address Range for Sec ID
The user segment of the Security ID can be programmed
in several ways. For smaller datasets, use the Security ID
Word-Program command for word-programming. To pro-
gram larger sets of data more quickly, use the SEC ID
Entry command to enter the Secure ID space. Once in the
Secure ID space, use the Write-Buffer Programming or
Bypass Mode feature. Note that the Word-Programming
command can also be used while in this mode.
To detect end-of-write for the SEC ID, read the toggle bits.
Do not use Data# Polling to detect end of Write. Once the
programming is complete, lock the Sec ID by issuing the
User Sec ID Program Lock-Out command or by program-
ming bit ‘0’ in the PSR with the PSR Program command.
Locking the Sec ID disables any corruption of this space.
Note that regardless of whether or not the Sec ID is locked,
the Sec ID segments can not 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 command should be executed. Refer
to Table 11 for software commands and Figures 27 and 28
for flow charts.
Bypass Mode
Bypass mode shortens the time needed to issue program
and erase commands by reducing these commands to two
write cycles each. After using the Bypass Entry command
to enter the Bypass mode, only the Bypass Word-Program,
Bypass Sector Erase, Bypass Block Erase, Bypass Chip
Erase, Erase-Suspend, and Erase-Resume commands
are available. The Bypass Exit command exits Bypass
mode. See Table 11 for further details.
Entering Bypass Mode while already in Erase-Suspend lim-
its the available commands. See “Erase-Suspend/Erase-
Resume Commands” on page 4 for more information.
