Alliance Memory M45PEx NOR Flash Memory Devices
Alliance Memory M45PEx NOR Flash Memory Devices are page-erasable serial flash memory with byte alterability and a 75MHz SPI bus interface. These memory devices can be accessed by a high-speed SPI-compatible bus. The M45PEx NOR flash utilizes the page write or page program instruction to write or program 1byte to 256bytes at a time. The page write instruction consists of an integrated page erase cycle followed by a page program cycle. This memory device offers a maximum clock rate of 75MHz, 64KB and 512KB sector erase, 256bytes page size, and JEDEC standard two-byte signature. The M45PEx NOR flash devices are available in a RoHS compliant package.Features
