GENERAL DESCRIPTION
The EN25F40A is a 4 Megabit (512 K-byte) Serial Flash memory, with enhanced write protection
mechanisms. The EN25F40A 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 104MHz are
supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual Output and 416MHz
(104MHz 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 EN25F40A is designed to allow either single Sector/Block at a time or full chip erase operation. The
EN25F40A 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.
