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). 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 ei-
ther in-system or via programming equipment. Figure 2 shows the algorithms and Figure 24
shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector
group unprotect, all unprotected 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 program-
ming and protecting 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 Autoselect
Mode for details.
Note: All sector groups are 256 Kwords in size.
