Summary description

The M25P10-A is a 1 Mbit (128K 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 4 sectors, each containing 128 pages. Each page is 256 bytes wide. Thus, the whole memory can be viewed as consisting of 512 pages, or 131,072 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.
