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.
