EN25Q128 is a 128 Megabit (16,384K-byte) Serial Flash memory, with advanced write protection mechanisms. The EN25Q128 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), DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock frequencies of up to 80MHz are supported allowing equivalent clock rates of 160MHz (80MHz x 2) for Dual Output when using the Dual Output Fast Read instructions, and SPI clock frequencies of up to 50MHz are supported allowing equivalent clock rates of 200MHz (50MHz x 4) for Quad Output when using the Quad Output Fast Read instructions. The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction. The EN25Q128 is designed to allow either single Sector/Block
