GENERAL DESCRIPTION
The EN25QH64 is a 64 Megabit (8,192 K-byte) Serial Flash memory, with enhanced write protection mechanisms. The EN25QH64 supports the standard Serial Peripheral Interface (SPI), and a high performance Dual/Quad output as well as Dual/Quad I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0(DI), DQ1(DO), DQ2(WP#) and DQ3(HOLD#). 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 80MHz are supported allowing equivalent clock rates of 320MHz (80MHz 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.
