Functions
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.
To transfer commands, addresses, or data serially into the device.
Inputs are latched on the rising edge of the serial clock.
To transfer data serially out of the device.
Data is shifted out on the falling edge of the serial clock.
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. These pins are for Dual I/O
mode.
The device is enabled by a high to low transition on CE#. CE# must remain low for
the duration of any command sequence.
The Write Protect (WP#) pin is used to enable/disable BPL bit in the status register.
To reset the operation of the device and the internal logic. The device powers on with
RST# pin functionality as default.
To temporarily stop serial communication with SPI Flash memory while device is
selected. This is selected by an instruction sequence. See “Reset/Hold Mode” page 5
for details.
To provide power supply voltage: 2.7-3.6V
