Sector Protection/Unprotection
The hardware sector protection feature disables both program and erase operations in any sector. The
hardware sector unprotection feature re-enables both program and erase operations in previously protected
sectors.
The device is shipped with all sectors unprotected. Spansion offers the option of programming and protecting
sectors at its factory prior to shipping the device through the Spansion ExpressFlash™ Service. Contact a
Spansion representative for further details.
It is possible to determine whether a sector is protected or unprotected. See
Sector protection/unprotection can be implemented via two methods.
The primary method requires V
programming equipment.
the timing diagram. This method uses standard microprocessor bus cycle timing. For sector unprotect, all
unprotected sectors must first be protected prior to the first sector unprotect write cycle.
The alternate method intended only for programming equipment requires V
This method is compatible with programmer routines written for earlier 3.0-volt-only Spansion flash devices.
Details on this method are provided in a supplement, publication number 21468. Contact a Spansion
representative to request a copy.
