Description

The M45PE10 is a 1 Mbit (128 Kb 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 followed by a Page Program cycle.

The 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 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 specifications are available at: www.st.com.

SO and VDFPN connections

There is an exposed central pad on the underside of the VFQFPN 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.

See Package mechanical section for package dimensions, and how to identify pin-1.
