Program-Suspend/
Program-Resume Command
The Program-Suspend and Program-Resume commands
have no influence on the device. Since the device requires
a maximum of T

the suspended Byte Program operation will always be suc-
cessfully completed within the suspend latency time (T

Security ID Commands
The SST49LF016C device offers a 256-bit Security ID
space. The Security ID space is divided into two parts. One
64-bit segment is programmed at SST with a unique 64-bit
number: this number cannot be changed by the user. The
other segment is 192-bit wide and is left blank: this space is
available for customers and can be programmed as
desired.
The User-Security-ID-Program command is shown in
Table 8, “Software Command Sequence”. Use the memory
addresses specified in Table 11 for Security ID program-
ming. Once the customer segment is programmed, it can
be locked to prevent any alteration. The User-Security-ID-
Program-Lockout command is shown in Table 8, “Software
Command Sequence”.
In order to read the Security ID information, the user can
issue a Read Security ID Command (90H) to the device. At
this point the device enters the Read-Software-ID/Read-
Security-ID mode. The Security ID information can be read
at the memory addresses in Table 11.
A Read-Array/Reset command (FFH) must then be issued
to the device in order to exit the Read-Software-ID/Read-
Security-ID mode and return to Read-Array mode.
An alternate method to read the Security ID information is
to read the Security ID registers located into the register
space as described in the “Security ID Registers” section.
