●Description

●The M45PE40 is a 4 Mbit (512 K x 8 bit) Serial Paged Flash Memory accessed by a high speed SPI-compatible bus. The memory can be written or programmed 1 to 256 bytes at a time, using the Page Write or Page Program instruction. The Page Write instruction consists of an integrated Page Erase cycle followed by a Page Program cycle.
