Low V
Unless otherwise specified, the device is shipped such that the customer may program and protect 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
on page
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:
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.
In devices with an ESN, the Secured Silicon Sector is protected when the device is shipped from the factory.
The Secured Silicon Sector cannot be modified in any way. An ESN Factory Locked device has an 16-byte
random ESN at addresses 000000h–000007h. Please contact your sales representative for details on
ordering ESN Factory Locked devices.
Customers may opt to have their code programmed by the factory through the ExpressFlash service (Express
Flash Factory Locked). The devices are then shipped from the factory with the Secured Silicon Sector
permanently locked. Contact your sales representative for details on using the ExpressFlash service.

The command sequence requirement of unlock cycles for programming or erasing provides data protection
against inadvertent writes (refer to
definitions). In addition, the following hardware data protection measures prevent accidental erasure or
programming, which might otherwise be caused by spurious system level signals during V
