Note that the WP#/ACC pin must not be left floating or
unconnected; inconsistent behavior of the device may
result.
Temporary Sector/Sector Block Unprotect
(Note: For the following discussion, the term
“
sector
”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Table
10).
This feature allows temporary unprotection of previ-
ously protected sectors to change data in-system. The
Sector Unprotect mode is activated by setting the RE-
SET# pin to V
ID
(11.5 V
–
12.5 V). During this mode,
formerly protected sectors can be programmed or
erased by selecting the sector addresses. Once V
ID
is
removed from the RESET# pin, all the previously pro-
tected sectors are protected again. Figure 1 shows the
algorithm, and Figure 25 shows the timing diagrams,
for this feature.

Notes:
1. All protected sectors unprotected (If WP#/ACC = V

,
outermost boot sectors will remain protected).
2. All previously protected sectors are protected once
again.
