SUMMARY DESCRIPTION

The M45PE10 is a 1Mbit (128K 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 2 sectors, each con-

taining 256 pages. Each page is 256 bytes wide.

Thus, the whole memory can be viewed as con-

sisting of 512 pages, or 131,072 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 these devices in ECOPACK® packages.

ECOPACK® packages are Lead-free and RoHS

compliant.

ECOPACK is an ST trademark. ECOPACK speci-

fications are available at: www.st.com.

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.

2. See PACKAGE MECHANICAL section for package di-

mensions, and how to identify pin-1.
