8.2 EN25QH16 16 Megabit Serial Flash Memory with 4Kbyte Uniform
Sector
Sector
8.2.1 General Description
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. The EN25QH16 is designed to allow either single
Sector/Block at a time or full chip erase operation. The EN25QH16 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.
