Write Protect (WP#)

The Write Protect function provides a hardware

method of protecting the first or last sector without

using V

ID.

If the system asserts V

IL on the WP# pin, the device

disables program and erase functions in the first or last

sector independently of whether those sectors were

protected or unprotected using the method described

in “Sector Group Protection and Unprotection”. Note

that if WP# is at V

IL when the device is in the standby

mode, the maximum input load current is increased.

See the table in “DC Characteristics”.

If the system asserts V

IH on the WP# pin, the device

reverts to whether the first or last sector was previ-

ously set to be protected or unprotected using the

method described in “Sector Group Protection and

Unprotection”.

Temporary Sector Group Unprotect

(Note: In this device, a sector group consists of four adjacent

sectors that are protected or unprotected at the same time

(see Table 4).

This feature allows temporary unprotection of previ-

ously protected sector groups to change data in-sys-

tem. The Sector Group Unprotect mode is activated by

setting the RESET# pin to V

ID. During this mode, for-

merly protected sector groups can be programmed or

erased by selecting the sector group addresses. Once

V

ID is removed from the RESET# pin, all the previously

protected sector groups are protected again. Figure 1

shows the algorithm, and Figure 24 shows the timing

diagrams, for this feature.

Notes:

1. All protected sector groups unprotected (If WP# = V

IL,

the first or last sector will remain protected).

2. All previously protected sector groups are protected

once again.
