Factory Secured Silicon Sector
The Factory Secured Silicon Sector is protected when the device is shipped from the factory. The Factory
Secured Silicon Sector cannot be modified in any way. The Factory Secured Silicon Sector is located at
addresses 000000h–00007Fh and is unprogrammed by default.
The device is available pre programmed with one of the following:
A random, secure ESN only within the Factory Secured Silicon Sector.
Customer code within the Customer Secured Silicon Sector through the Spansion programming services.
Both a random, secure ESN and customer code through the Spansion programming services.
Customers may opt to have their code programmed by Spansion through the Spansion programming
services. Spansion programs the customer’s code, with or without the random ESN. The devices are then
shipped from Spansion’s factory with the Factory Secured Silicon Sector and Customer Secured Silicon
Sector permanently locked. Contact a Spansion representative for details on using Spansion’s programming
services.
Customer Secured Silicon Sector
If the security feature is not required, the Customer Secured Silicon Sector can be treated as an additional
Flash memory space. The Customer Secured Silicon Sector can be read any number of times, but can be
programmed and locked only once. Note that the accelerated programming (VPP) function is not available
when programming the Customer Secured Silicon Sector, but reading the first Bank through the last bank is
available. The Customer Secured Silicon Sector is located at addresses 000080h–0000FFh.
The Customer Secured Silicon Sector area can be protected by writing the Secured Silicon Sector Protection
Bit Lock command sequence.
Once the Customer 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 SA0 in the memory array.
The Customer Secured Silicon Sector lock must be used with caution since, once locked, there is no
procedure available for unlocking the Customer Secured Silicon Sector area and none of the bits in the
Customer Secured Silicon Sector memory space can be modified in any way.
