Description

The M25PE80 is an 8 Mbit (1 Mb × 8) 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 that are further divided up into 16 subsectors each (256 subsectors in total). Each sector contains 256 pages and each subsector contains 16 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, a subsector at a time, using the SubSector Erase instruction, a sector at a time, using the Sector Erase instruction, or as a whole, using the Bulk Erase instruction.

The memory can be Write Protected by either Hardware or Software using a mix of volatile and non-volatile protection features, depending on the application needs. The protection granularity is of 64 Kbytes (sector granularity).

In order to meet environmental requirements, ST offers the M25PE80 in ECOPACK® packages. ECOPACK® packages are Lead-Free and RoHS compliant.
