SSIGNMENTS FOR
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.
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 resetting the device.
To provide power supply voltage: 3.0-3.6V for SST25LF080A
