Memory Organization
The memory is organized in the following
manner:
•= 131,072 bytes (8 bits each)
•= 4 sectors (256 Kb, 32,768 bytes
each), as shown in Table 1
Each page can be individually
programmed, with the bits programmed
from 1 to 0. The SA25F010's memory can
be erased via the Page, Sector or Bulk
Erase commands, with the bits erased
from 0 to 1.
•= 512 pages (256 bytes each)
