Description
The M45PE40 is a 4 Mbit (512 K x 8 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.
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 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.
In order to meet environmental requirements, Numonyx offers the M45PE40 in ECOPACK®
packages. ECOPACK® packages are Lead-free and RoHS compliant.
