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 DQ
0
(DI),
DQ
1
(DO), DQ
2
(WP#) and DQ
3
(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
.

SIGNAL DESCRIPTION
Serial Data Input, Output and IOs (DI, DO and DQ
0
, DQ
1
, DQ
2
, DQ
3
)
The EN25Q80A 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 enables and disables device operation. When CS# is high the device is
deselected and the Serial Data Output (DO, or DQ
0
, DQ
1
, DQ
2
and DQ
3
) pins are at high impedance.
When deselected, the devices power consumption will be at standby levels unless an internal erase,
program or status register cycle is in progress. When CS# is brought low the device will be selected,
power consumption will increase to active levels and instructions can be written to and data read from
the device. After power-up, CS# must transition from high to low before a new instruction will be
accepted.
Write Protect (WP#)
The Write Protect (WP#) pin can be used to prevent the Status Register from being written. Used in
conjunction with the Status Register’s Block Protect (BP0, BP1and BP2) bits and Status Register
Protect (SRP) bits, a portion or the entire memory array can be hardware protected. The WP# function
is only available for standard SPI and Dual SPI operation, when during Quad SPI, this pin is the Serial
Data IO (DQ
2
) for Quad I/O operation.

or modifications due to changes in technical specifications.
