Electronic Signatures
The memory can be programmed 1 to 256 bytes at a time, using
the Page Program instruction.
The memory is organized as 8 sectors, each containing 256
pages. Each page is 256 bytes wide. Thus, the whole memory
can be viewed as consisting of 2048 pages, or 524,288 bytes.
The whole memory can be erased using the Bulk Erase
instruction, or a sector at a time, using the Sector Erase
instruction.
