Name

Functions

SCK Serial

Clock

To provide the timing for serial input and
output operations

Serial Data Input

To transfer commands, addresses or data
serially into the device.
Data is latched on the rising edge of SCK.

Serial Data Output

To transfer data serially out of the device.
Data is shifted out on the falling edge of
SCK.

Chip Enable

To activate the device when CE is low.

Write Protect

The Write Protect ( WP ) pin is used to
enable/disable BPL bit in the status
register.

HOLD

Hold

To temporality stop serial communication
with SPI flash memory without resetting
the device.

VDD

Power Supply

To provide power.

VSS Ground
