描述 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-byte wide. Thus, the whole memory can be viewed as consisting

of 4096 pages, or 1 048 576 bytes.
