GENERAL DESCRIPTION
   The EN25S80A is an 8 Megabit (1024K-byte) Serial Flash memory, with advanced write protection mechanisms. The EN25S80A supports the standard Serial Peripheral Interface (SPI), and a high performance Dual output as well as Dual, Quad I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0 (DI) and DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock frequencies of up to 104MHz are supported allowing equivalent clock rates of 208MHz for Dual Output and 416MHz for Quad Output when using the Dual/Quad Output Fast Read instructions. The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction.
