M25P20-VMN3 Datasheet PDF - Numonyx

●Summary description

●The M25P20 is a 2 Mbit (256K 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 256 pages. Each page is 256 bytes wide. Thus, the whole memory can be viewed as consisting of 1024 pages, or 262,144 bytes.

●The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction.
