Functions

SCK

Serial Clock

To 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 is shifted out on the falling edge of the clock input.

SIO[3:0]

Serial Data

Input/Output

To 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 is

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.

Serial Data Input

for SPI mode

To 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.

Serial Data Output

for SPI mode

To 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.

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.

WP#

Write Protect

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

tion register to prohibit write operations to the Block-Protection register. This pin

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

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

To provide power supply voltage.
