M25PE40-VMN6P Datasheet PDF - Numonyx -> Micron

 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.
