Summary description

The M25P128 is a multilevel 128Mbit (16Mbit x 8) Serial Flash Memory, with advanced write

protection mechanisms, accessed by a high speed SPI-compatible bus.

The memory can be programmed 1 to 256 bytes at a time, using the Page Program

instruction.

The memory is organized as 64 sectors, each containing 1024 pages. Each page is 256

bytes wide. Thus, the whole memory can be viewed as consisting of 65536 pages, or

16777216 bytes.

The whole memory can be erased using the Bulk 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.
