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.

SIGNAL DESCRIPTION Serial Data Input, Output and IOs (DI, DO and DQ0, DQ1, DQ2, DQ3) The EN25QH16 support standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to read data or status from the device on the falling edge CLK. Dual and Quad SPI instruction use the bidirectional IO pins to serially write instruction, addresses or data to the device on the rising edge of CLK and read data or status from the device on the falling edge of CLK. Serial Clock (CLK) The SPI Serial Clock Input (CLK) pin provides the timing for serial input and output operations. ("See SPI Mode") Chip Select (CS#) The SPI Chip Select (CS#) pin enabl.
