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.
Data is shifted out on the falling edge of the serial clock.
Outputs Flash busy status during AAI Programming when reconfigured as RY/
BY# pin. See “Hardware End-of-Write Detection” on page 13 for details.
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 temporarily stop serial communication with SPI flash memory without reset-
ting the device.
To provide power supply voltage: 2.7-3.6V for SST25VF080B
