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 EQIO command
instruction configures these pins for Quad I/O mode.
SI
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.
SO
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 oper-
ations, for the command/data input sequence.
VDD
Power Supply
To provide power supply voltage: 1.65-1.95V
