Sector Protection/Unprotection
The hardware sector protection feature disables both program and erase opera-
tions 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 Spansion’s ExpressFlash™ Service. Contact an Spansion representative
for details.
It is possible to determine whether a sector is protected or unprotected. See
Autoselect Mode, on page 15 for details.
Sector Protection/unprotection can be implemented via two methods.
The primary method requires VID on the RESET# pin only, and can be imple-
mented either in-system or via programming equipment. Figure 2, on page 18
shows the algorithms and Figure 23, on page 47 shows 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 VID on
address pin A9 and OE#. This method is compatible with programmer routines
written for earlier 3.0 volt-only Spansion flash devices. Publication number 20536
contains further details; contact an Spansion representative to request a copy.
Temporary Sector Unprotect
This feature allows temporary unprotection of previously protected sectors to
change data in-system. The Sector Unprotect mode is activated by setting the
RESET# pin to VID. During this mode, formerly protected sectors can be pro-
grammed or erased by selecting the sector addresses. Once VID is removed from
the RESET# pin, all the previously protected sectors are protected again.
