kr M25PXX SUMMARY DESCRIPTION The M25Pxx is a 512Kbit to 32Mbit (2M 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 a number of sectors, each containing 256 or 128 pages.
Each page is 256 bytes wide.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction.
