M45PE80

SUMMARY DESCRIPTION

The M45PE80 is a 8Mbit (1M 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 16 sectors, each con-

taining 256 pages. Each page is 256 bytes wide.

Thus, the whole memory can be viewed as con-

sisting 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.

Note: 1. There is an exposed die paddle on the underside of the

MLP8 package. This is pulled, internally, to VSS, and

must not be allowed to be connected to any other voltage

or signal line on the PCB.

mensions, and how to identify pin-1.
