Security ID Registers
The SST49LF016C device offers a 256-bit Security ID reg-
ister space. The Security ID space is divided into two seg-
ments - one (64-bits) factory programmed segment and
one (192 bits) user programmed segment. The first seg-
ment is programmed and locked at SST with a unique 64-
bit number. The user segment (192 bits) is left blank (FFH)
for the customer to be programmed as desired. Refer to
Table 8, “Software Command Sequence” for more details.
The Security ID Information and its Write Lock/Unlock sta-
tus can be Read in the Register Access Space for Execute-
In-Place type of applications. (See Table 16.)
TABLE 16: Security ID Registers
JEDEC ID Registers
The JEDEC ID registers for the boot device appear at
FFBC0000H and FFBC0001H in the 4 GByte system
memory map, and will appear elsewhere if the device is not
the boot device. This register is not available to be read
when the device is in Erase/Program operation. Unused
register location will read as 00H. See Table 17 for the
JEDEC device ID code. In case of multi-byte register reads
with Firmware Memory cycle, the device will return register
data for the addressed register until the command finishes,
or is aborted.

Access
The Write Lock-out status of the Security ID space can be
read from the SEC_ID_WRITE_LOCK register (see Table
16). The SEC_ID_WRITE_LOCK register is a read-only
register that is accessible at the address location specified
in Table 16.
In case of multi-byte register reads with Firmware Memory
cycle, for SEC_ID_WRITE_LOCK register, the device will
return register data for the addressed register until the com-
mand finishes, or is aborted.
In the case of multi-byte register reads with Firmware
Memory cycle, for all the SEC_ID_BYTE registers, the
device will return page-aligned sequential register data with
wrap-around until the command finishes, or is aborted.
