Hardware Data Protection Methods
WP# Method
Low V
Write Pulse Glitch Protection
Power-Up Write Inhibit
The device offers data protection at the sector level via hardware control:
There are additional methods by which intended or accidental erasure of any sectors can be prevented via
hardware means. The following subsections describes these methods:
The Write Protect feature provides a hardware method of protecting the four outermost sectors. This function
is provided by the WP#/ACC pin and overrides the previously discussed Sector Protection/Unprotection
method.
If the system asserts V

of sectors in a dual-boot-configured device.
If the system asserts V
be protected or unprotected. That is, sector protection or unprotection for these sectors depends on whether
they were last protected or unprotected.
Note that the WP#/ACC pin must not be left floating or unconnected as inconsistent behavior of the device
may result.
The WP#/ACC pin must be held stable during a command sequence execution

The command register and all internal program/erase circuits are disabled, and the device resets to reading
array data. Subsequent writes are ignored until V
