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 Express-  
Flash™ Service. Contact a Spansion representative for further details.  
It is possible to determine whether a sector is protected or unprotected. See “Autoselect Mode”  
for details.  
Sector protection/unprotection can be implemented via two methods.  
The primary method requires V on the RESET# pin only, and can be implemented either in-sys-  
ID  
tem or via programming equipment. Figure 2, on page 25 shows the algorithms and Figure 26,  
on page 59 shows the timing diagram. This method uses standard microprocessor bus cycle tim-  
ing. 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 on address pin A9  
ID  
and OE#. 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.
