SUMMARY DESCRIPTION
The M45PE20 is a 2Mbit (256K 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 fol-
lowed by a Page Program cycle.
The memory is organized as 4 sectors, each con-
taining 256 pages. Each page is 256 bytes wide.
Thus, the whole memory can be viewed as con-
sisting of 1024 pages, or 262,144 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.
