Serial Number (ESN). The Secured Silicon Sector is 128
words in length and all Secured Silicon reads outside of the
128-word address range returns invalid data. The Secured
Silicon Sector Indicator Bit, DQ7, (at Autoselect address
03h) is used to indicate whether or not the Secured Silicon
Sector is locked when shipped from the factory.
Please note the following general conditions:
On power-up, or following a hardware reset, the
device reverts to sending commands to the normal
address space.
Reads outside of sector SA0 return memory array
data.
Sector SA0 is remapped from memory array to
Secured Silicon Sector array.
Once the Secured Silicon Sector Entry Command
is issued, the Secured Silicon Sector Exit command
must be issued to exit Secured Silicon Sector Mode.
The Secured Silicon Sector is not accessible when
the device is executing an Embedded Program or
Embedded Erase algorithm.
The ACC function and unlock bypass modes are
not available when the Secured Silicon Sector is
enabled.
FACTORY LOCKED SECURED SILICON
SECTOR
The Factory Locked Secured Silicon Sector is always
protected when shipped from the factory and has the
Secured Silicon Sector Indicator Bit (DQ7) permanently set
to a “1”. This prevents cloning of a factory locked part and
ensures the security of the ESN and customer code once
the product is shipped to the eld.
These devices are available pre-programmed with one of
the following:
A random, 8 Word secure ESN only within the
Secured Silicon Sector (at addresses 000000H -
000007H)
Both a random, secure ESN and customer code
through the Spansion programming service.
Customers may opt to have their code programmed through
the Spansion programming services. Spansion programs
the customer's code, with or without the random ESN. The
devices are then shipped from the Spansion factory with
the Secured Silicon Sector permanently locked. Contact
your local representative for details on using Spansion
programming services.
CUSTOMER LOCKABLE SECURED
SILICON SECTOR
The Customer Lockable Secured Silicon Sector is always
shipped unprotected (DQ7 set to “0”), allowing customers to
utilize that sector in any manner they choose. If the security
feature is not required, the Secured Silicon Sector can be
treated as an additional Flash memory space.
Please note the following:
Once the Secured Silicon Sector area is protected,
the Secured Silicon Sector Indicator Bit is
permanently set to “0.”
The Secured Silicon Sector can be read any number
of times, but can be programmed and locked only
once. The Secured Silicon Sector lock must be used
with caution as 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 modied in any way.
The accelerated programming (ACC) and unlock
bypass functions are not available when the Secured
Silicon Sector is enabled.
Once the Secured Silicon Sector is locked and
veried, the system must write the Exit Secured
Silicon Sector Region command sequence which
return the device to the memory array at sector 0.
SECURED SILICON SECTOR ENTRY/
EXIT COMMAND SEQUENCES
The system can access the Secured Silicon Sector region
by issuing the three-cycle Enter Secured Silicon Sector
command sequence. The device continues to access
the Secured Silicon Sector region until the system issues
the four-cycle Exit Secured Silicon Sector command
sequence.
See Command Definitions [Secured Silicon Sector
Command Table, Appendix
Table 39 for address and data requirements for both
command sequences.
The Secured Silicon Sector Entry Command allows the
following commands to be executed
Read customer and factory Secured Silicon areas
Program the customer Secured Silicon Sector
