Product Summary

The EN25QH16 is a 16 Megabit (2,048 K-byte) Serial Flash memory, with enhanced write protection
mechanisms. The EN25QH16 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 and 320MHz
(80MHz x 4) for Quad Output when using the Dual/Quad I/O Fast Read instructions. The memory can
be programmed 1 to 256 bytes at a time, using the Page Program instruction.
