M25P40 4 Mbit/ Low Voltage/ Serial Flash Memory

The M25P40 is a 4 Mbit (512K 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 8 sectors, each containing 256 pages. Each page is 256 bytes wide. Thus, the whole memory can be vi.
