Write Protect / Accelerated Program (WP# / ACC)
The WP#/ACC pin provides two functions. The Write Protect (WP#) function provides a hardware method
of protecting the outermost two 8K-byte Boot Sector. The ACC function allows faster manufacturing
throughput at the factory, using an external high voltage.
When WP#/ACC is Low, the device protects the outermost tw 8K-byte Boot Sector; no matter the sectors
are protected or unprotected using the method described in “Sector/Sector Group Protection & Chip
Unprotection”, Program and Erase operations in these sectors are ignored.
When WP#/ACC is High, the device reverts to the previous protection status of the outermost two 8K-byte
boot sector. Program and Erase operations can now modify the data in the two outermost 8K-byte Boot
Sector unless the sector is protected using Sector Protection.
When WP#/ACC is raised to V
HH
the memory automatically enters the Unlock Bypass mode(please refer
to “Command Definitions”), temporarily unprotects every protected sectors, and reduces the time required
for program operation. The system would use a two-cycle program command sequence as required by
the Unlock Bypass mode. When WP#/ACC returns to V
IH
or V
IL
, normal operation resumes. The
transitions from V
IH
or V
IL
to V
HH
and from V
HH
to V
IH
or V
IL
must be slower than tB
VHHB
, see Figure 11.
Note that the WP#/ACC pin must not be left floating or unconnected. In addition, WP#/ACC pin must not
be at V
HH
for operations other than accelerated programming. It could cause the device to be damaged.
Never raise this pin to V
HH
from any mode except Read mode, otherwise the memory may be left in an
indeterminate state.
