Chip Erase
The entire main memory can be erased at one time by using the Chip Erase command.
To execute the Chip Erase command, a 4-byte command sequence C7H, 94H, 80H and 9AH must be clocked into
the device. Since the entire memory array is to be erased, no address bytes need to be clocked into the device,
and any data clocked in after the opcode will be ignored. After the last bit of the opcode sequence has been
clocked in, the CS pin can be deasserted to start the erase process. The erase operation is internally self-timed
and should take place in a time of t
The Chip Erase command will not affect sectors that are protected or locked down; the contents of those sectors
will remain unchanged. Only those sectors that are not protected or locked down will be erased.
Note:
The WP pin can be asserted while the device is erasing, but protection will not be activated until the internal erase
cycle completes.
