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 VHH 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 VIH or VIL, normal operation resumes. The
transitions from VIH or VIL to VHH and from VHH to VIH or VIL must be slower than tBVHHB, 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 VHH for operations other than accelerated programming. It could cause the device to be damaged.
Never raise this pin to VHH from any mode except Read mode, otherwise the memory may be left in an
indeterminate state.
