Sector Group Protection and Unprotection
The hardware sector group protection feature disables both program and erase operations in any sector group.
In this device, a sector group consists of four adjacent sectors that are protected or unprotected at the same time
(see Table 4 on page 28). The hardware sector group unprotection feature re-enables both program and erase
operations in previously protected sector groups. Sector group protection/unprotection can be implemented via
two methods.
Sector protection/unprotection requires VID on the RESET# pin only, and can be implemented either in-system or
via programming equipment. Figure 2, on page 96 shows the algorithms and Figure 24, on page 140 shows the
timing diagram. This method uses standard microprocessor bus cycle timing. For sector group unprotect, all un-
protected sector groups must first be protected prior to the first sector group unprotect write cycle.
The device is shipped with all sector groups unprotected. Spansion offers the option of programming and protect-
ing sector groups at its factory prior to shipping the device through Spansion Programming Service. Contact a
Spansion representative for details.
It is possible to determine whether a sector group is protected or unprotected. See the “Autoselect Mode” on
page 79 section for details.
Note: All sector groups are 256 Kbytes in size.
