The M45PE40 is a 4-Mbit (512 Kbit x8 bit) serial paged flash memory accessed by a high speed SPI-compatible bus. The memory can be written or programmed 1 to 256 bytes at a time, using the page write or page program instruction. The page write instruction consists of an integrated page erase cycle followed by a page program cycle.
M45PE40 is organized as 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 524288 bytes. The memory can be erased a page at a time, using the page erase instruction, or a sector at a time, using the sector erase instruction.
