SUMMARY DESCRIPTION
The M25PE20 and M25PE10 are 2 Mbit (256K x 8
bit) and 1 Mbit (128K x8 bit) Serial Paged Flash
Memories, respectively. They are accessed by a
high speed SPI-compatible bus.
The memories 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 M25PE20 memory is organized as 4 sectors,
each containing 256 pages. Each page is 256
Bytes wide. Thus, the whole memory can be
viewed as consisting of 1024 pages, or 262,144
Bytes.
The M25PE10 memory is organized as 2 sectors,
each containing 256 pages. Each page is 256
Bytes wide. Thus, the whole memory can be
viewed as consisting of 512 pages, or 131, 072
Bytes.
The memories can be erased a page at a time, us-
ing the Page Erase instruction, or a sector at a
time, using the Sector Erase instruction.
The top sector of the memories can be Write Pro-
tected by Hardware (TSL).
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 V
SS
, 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.
