Per data sheet:
– Normal Read (Serial):
– 50 MHz clock rate (-40°C to +85°C/105°C)
– 45 MHz clock rate (-40°C to +125°C)
– Fast Read (Serial):
– 108 MHz clock rate (-40°C to +85°C/105°C)
– 97 MHz clock rate (-40°C to +125°C)
– Dual Read:
– 108 MHz clock rate (-40°C to +85°C/105°C)
– 97 MHz clock rate (-40°C to +125°C)
– Quad Read:
– 108 MHz clock rate (-40°C to +85°C/105°C)
– 97 MHz clock rate for S25FL164K (-40°C to +125°C)
- Clock frequency for all SPI commands except for Read Data
command (0x03) and Fast Read command (0x0b): 108 MHz
- Clock frequency for Read Data command (0x03): 50 MHz
- Clock frequency for all Fast Read commands SIO and MIO: 108 MHz
In this implementation, only "Quad" reads are performed.
