10. Secured Silicon Sector Flash Memory Region

Factory Locked Secured SiliconSector
Customer Lockable Secured Silicon Sector
The Secured Silicon Sector provides an extra Flash memory region that enables permanent part identification
through an Electronic 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:
The 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 field.
These devices are available pre-programmed with one of the following:
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.
The Secured Silicon Sector is typically 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:
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.
Secured Silicon Sector
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.
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 modified in any way.
The accelerated programming (ACC) and unlock bypass functions are not available when the Secured
Silicon Sector is enabled.
