Info rmation
Factory-Locked Area (64 words)
The factory-locked area of the Secured Silicon Sector (000000h-00003Fh) is
locked when the part is shipped, whether or not the area was programmed at the
factory. The Secured Silicon Sector Factory-locked Indicator Bit (DQ7) is perma-
nently set to a “1”. Optional Spansion programming services can program the
factory-locked area with a random ESN, a customer-defined code, or any combi-
nation of the two. Because only FASL can program and protect the factory-locked
area, this method ensures the security of the ESN once the product is shipped to
the field. Contact your local sales office for details on using Spansion’s program-
ming services. Note that the ACC function and unlock bypass modes are not
available when the Secured Silicon sector is enabled.
Customer-Lockable Area (64 words)
The customer-lockable area of the Secured Silicon Sector (000040h-00007Fh) is
shipped unprotected, which allows the customer to program and optionally lock
the area as appropriate for the application. The Secured Silicon Sector Customer-
locked Indicator Bit (DQ6) is shipped as “0” and can be permanently locked to “1”
by issuing the Secured Silicon Protection Bit Program Command. The Secured Sil-
icon Sector can be read any number of times, but can be programmed and locked
only once. Note that the accelerated programming (ACC) and unlock bypass func-
tions are not available when programming the Secured Silicon Sector.
The Customer-lockable Secured Silicon Sector area can be protected using one
of the following procedures:
Write the three-cycle Enter Secured Silicon Sector Region command se-
quence, and then follow the in-system sector protect algorithm as shown in
Figure 1, except that RESET# may be at either VIH or VID. This allows in-sys-
tem protection of the Secured Silicon Sector Region without raising any de-
vice pin to a high voltage. Note that this method is only applicable to the
Secured Silicon Sector.
To verify the protect/unprotect status of the Secured Silicon Sector, follow the
algorithm shown in Figure 3.
Once the Secured Silicon Sector is locked and verified, the system must write the
Exit Secured Silicon Sector Region command sequence to return to reading and
writing the remainder of the array.
The Secured Silicon Sector lock must be used with caution since, once locked,
there is no procedure available for unlocking the Secured Silicon Sector area and
none of the bits in the Secured Silicon Sector memory space can be modified in
any way.
Secured Silicon Sector Protection Bits
The Secured Silicon Sector Protection Bits prevent programming of the Secured
Silicon Sector memory area. Once set, the Secured Silicon Sector memory area
contents are non-modifiable.
