4Mbit, page-erasable serial Flash memory with byte alterability, 75MHz SPI bus, standard pinout
Description
The M25PE40 is a 4 Mbit 512Kbit × 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.
