Secured Silicon Sector Flash Memory Region
The Secured Silicon Sector feature provides a Flash memory region that enables permanent part
identification through an Electronic Serial Number (ESN). The Secured Silicon Sector is 256 bytes
in length, and uses a Secured Silicon Sector Indicator Bit (DQ7) to indicate whether or not the
Secured Silicon Sector is locked when shipped from the factory. This bit is permanently set at the
factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the
security of the ESN once the product is shipped to the field.
The factory offers the device with the Secured Silicon Sector either customer lockable (standard
shipping option) or factory locked (contact a Spansion sales representative for ordering informa-
tion). The customer-lockable version is shipped with the Secured Silicon Sector unprotected,
allowing customers to program the sector after receiving the device. The customer-lockable ver-
sion also has the Secured Silicon Sector Indicator Bit permanently set to a “0.” The factory-locked
version is always protected when shipped from the factory, and has the Secured Silicon (Secured
Silicon) Sector Indicator Bit permanently set to a “1.” Thus, the Secured Silicon Sector Indicator
Bit prevents customer-lockable devices from being used to replace devices that are factory
locked.
Note: The ACC function and unlock bypass modes are not available when the Secured Silicon Sector is enabled.
The Secured Silicon sector address space in this device is allocated as follows:
The system accesses the Secured Silicon Sector through a command sequence (see Write Protect
(WP#)). After the system writes the Enter Secured Silicon Sector command sequence, it may read
the Secured Silicon Sector by using the addresses normally occupied by the first sector (SA0).
This mode of operation continues until the system issues the Exit Secured Silicon Sector com-
mand sequence, or until power is removed from the device. On power-up, or following a hardware
reset, the device reverts to sending commands to sector SA0.
Customer Lockable: Secured Silicon Sector Not Programmed or Protected At the Factory
Unless otherwise specified, the device is shipped such that the customer may program and pro-
tect the 256-byte Secured Silicon sector.
The system may program the Secured Silicon Sector using the write-buffer, accelerated and/or
unlock bypass methods, in addition to the standard programming command sequence (see Com-
Programming and protecting the Secured Silicon Sector must be used with caution since, once
protected, there is no procedure available for unprotecting the Secured Silicon Sector area and
none of the bits in the Secured Silicon Sector memory space can be modified in any way.
The Secured Silicon Sector area can be protected using one of the following procedures:
Write the three-cycle Enter Secured Silicon Sector Region command sequence, and then fol-
low the in-system sector protect algorithm as shown in Figure 2, except that RESET# may be
at either VIH or VID. This allows in-system protection of the Secured Silicon Sector without
raising any device pin to a high voltage. Note that this method is only applicable to the Se-
cured Silicon Sector.
Write the three-cycle Enter Secured Silicon Sector Region command sequence and then use
the alternate method of sector protection described in the “Sector Group Protection and Un-
protection” section.
Once the Secured Silicon Sector is programmed, locked, and verified, the system must write the
Exit Secured Silicon Sector Region command sequence to return to reading and writing within the
remainder of the array.
