Summary description

M45PE80

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, ST offers the M45PE80 in ECOPACK®

packages. ECOPACK® packages are Lead-free and RoHS compliant.

ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.
