Memory Configuration and Block Diagram
Each page of memory can be individually programmed. Bits are programmed from one
through zero. The device is subsector, sector, or bulk-erasable, but not page-erasable.
Bits are erased from zero through one. The memory is configured as 33,554,432 bytes (8
bits each); 512 sectors (64KB each); 8192 subsectors (4KB each); and 131,072 pages (256
bytes each); and 64 OTP bytes are located outside the main memory array.
