SecSi (Secured Silicon) Sector Flash Memory Region
The SecSi (Secured Silicon) Sector feature provides a Flash memory region that enables permanent part identi-
fication through an Electronic Serial Number (ESN). The SecSi Sector is 256 bytes in length, and uses a SecSi
Sector Indicator Bit (DQ7) to indicate whether or not the SecSi 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 SecSi Sector either customer lockable (standard shipping option) or factory
locked (contact a Spansion sales representative for ordering information). The customer-lockable version is
shipped with the SecSi Sector unprotected, allowing customers to program the sector after receiving the device.
The customer-lockable version also has the SecSi Sector Indicator Bit permanently set to a “0.” The factory-locked
version is always protected when shipped from the factory, and has the SecSi (Secured Silicon) Sector Indicator
Bit permanently set to a “1.” Thus, the SecSi Sector Indicator Bit prevents customer-lockable devices from being
used to replace devices that are factory locked. Note that the ACC function and unlock bypass modes are not
available when the SecSi Sector is enabled.
The SecSi sector address space in this device is allocated as follows:
The system accesses the SecSi Sector through a command sequence (see “Write Protect (WP#)”). After the sys-
tem has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses
normally occupied by the first sector (SA0). This mode of operation continues until the system issues the Exit
SecSi Sector command sequence, or until power is removed from the device. On power-up, or following a hard-
ware reset, the device reverts to sending commands to sector SA0.
Customer Lockable: SecSi Sector NOT Programmed or Protected At the Factory
Unless otherwise specified, the device is shipped such that the customer may program and protect the 256-byte
SecSi sector.
The system may program the SecSi Sector using the write-buffer, accelerated and/or unlock bypass methods, in
addition to the standard programming command sequence. See Command Definitions.
Programming and protecting the SecSi Sector must be used with caution since, once protected, there is no pro-
cedure available for unprotecting the SecSi Sector area and none of the bits in the SecSi Sector memory space
can be modified in any way.
The SecSi Sector area can be protected using one of the following procedures:
Write the three-cycle Enter SecSi Sector Region command sequence, and then follow the in-system
allows in-system protection of the SecSi Sector without raising any device pin to a high voltage. Note
that this method is only applicable to the SecSi Sector.
To verify the protect/unprotect status of the SecSi Sector, follow the algorithm shown in Figure 1.
Once the SecSi Sector is programmed, locked and verified, the system must write the Exit SecSi Sector Region
command sequence to return to reading and writing within the remainder of the array.
