GENERAL DESCRIPTION
The EN25S80 is an 8 Megabit (1024K-byte) 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 EN25S80 is designed to allow either single Sector/Blockat a time or full chip erase operation. TheEN25S80 can be configured to protect part of the memory as the software protected mode. The device can sustain a minimum of 100K program/erase cycles on each sector or block.
