Summary description
The M45PE80 is a 8 Mbit (1 Mbit × 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 16 sectors, each containing 256 pages. Each page is 256
bytes wide. Thus, the whole memory can be viewed as consisting of 4096 pages, or 1 048
576 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 M45PE80 in ECOPACK®
packages. ECOPACK® packages are Lead-free and RoHS compliant.
