Legend: L = Logic Low = VIL, H = Logic High = VIH, SA = Sector Address, X = Don’t care.
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 pro-
tected 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
either in-system or via programming equipment. Figure 2 shows the algorithms and Figure
23 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 pro-
gramming 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 the Au-
toselect Mode section for details.
