Symbol

Pin Name

Functions

CE#

Chip Enable

The device is enabled by a high-to-low transition on CE#. CE# must remain low for

the duration of any command sequence; or in the case of Write operations, for the

command/data input sequence.

Serial Data Output

for SPI mode

Transfer data serially out of the device. Data is shifted out on the falling edge of the

serial clock. SO is the default state after a Power-on Reset.

SIO[3:0]

Serial Data

Input/Output

Transfer commands, addresses or data serially into the device or data out of the

device. Inputs are latched on the rising edge of the serial clock. Data are shifted out

on the falling edge of the serial clock. The Enable Quad I/O (EQIO) command

instruction configures these pins for Quad I/O mode.

WP#

Write-Protect

The WP# is used in conjunction with the WPEN and IOC bits in the Configuration

works in SPI, single-bit and dual-bit Read mode.

VSS

Ground

Serial Data Input

for SPI mode

Transfer commands, addresses or data serially into the device. Inputs are latched on

the rising edge of the serial clock. SI is the default state after a Power-on Reset.

SCK

Serial Clock

Provide the timing of the serial interface.

Commands, addresses or input data are latched on the rising edge of the clock input,

while output data are shifted out on the falling edge of the clock input.

HOLD#

Hold

Temporarily stops serial communication with the SPI Flash memory while the device

is selected. This pin only works in SPI, single-bit and dual-bit Read mode and must

be tied high when not in use.

VDD

Power Supply

Provide power supply voltage.
