GENERAL DESCRIPTION
The EN25Q80A is an 8 Megabit (1024K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q80A supports the standard Serial Peripheral Interface (SPI), and a high
performance Dual output as well as Quad I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0(DI),
DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock frequencies of up to 80MHz are supported allowing
equivalent clock rates of 160MHz for Dual Output and 320MHz for Quad Output when using the
Dual/Quad Output Fast Read instructions. The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction.
The EN25Q80A is designed to allow either single Sector/Block at a time or full chip erase operation. The
EN25Q80A 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.

OPERATING FEATURES
EN25Q80A
Standard SPI Modes
The EN25Q80A is accessed through an SPI compatible bus consisting of four signals: Serial Clock
(CLK), Chip Select (CS#), Serial Data Input (DI) and Serial Data Output (DO). Both SPI bus operation
Modes 0 (0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and Mode 3, as
shown in Figure 3, concerns the normal state of the CLK signal when the SPI bus master is in standby
and data is not being transferred to the Serial Flash. For Mode 0 the CLK signal is normally low. For
Mode 3 the CLK signal is normally high. In either case data input on the DI pin is sampled on the rising
edge of the CLK. Data output on the DO pin is clocked out on the falling edge of CLK.
Figure 3. SPI Modes
Dual SPI Instruction
The EN25Q80A supports Dual SPI operation when using the “ Dual Output Fast Read and Dual I/O
Fast Read “ (3Bh and BBh) instructions. These instructions allow data to be transferred to or from the
Serial Flash memory at two to three times the rate possible with the standard SPI. The Dual Read
instructions are ideal for quickly downloading code from Flash to RAM upon power-up (code-shadowing)
or for application that cache code-segments to RAM for execution. The Dual output feature simply
allows the SPI input pin to also serve as an output during this instruction. When using Dual SPI
instructions the DI and DO pins become bidirectional I/O pins; DQ0 and DQ1. All other operations use
the standard SPI interface with single output signal.
Quad SPI Instruction
The EN25Q80A supports Quad output operation when using the Quad I/O Fast Read (EBh).This
instruction allows data to be transferred to or from the Serial Flash memory at four to six times the rate
possible with the standard SPI. The Quad Read instruction offer a significant improvement in
continuous and random access transfer rates allowing fast code-shadowing to RAM or for application
that cache code-segments to RAM for execution. The EN25Q80A also supports full Quad Mode
function while using the Enable Quad I/O (EQIO) (38h). When using Quad SPI instruction the DI and
DO pins become bidirectional I/O pins; DQ0 and DQ1, and the WP# and NC pins become DQ2 and DQ3
respectively.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
