I am struggling to find the minimum setup and hold timings for single-ended 3.3V LVCMOS inputs in the datasheet. I'm especially puzzled that the datasheet and handbook differentiate between low-speed and high-speed pins without stating the actual difference between the two.

I really would like to have some ballpark numbers prior to coding.

  • \$\begingroup\$ I presume you are talking about P34 of that document. If so did you read the paragraph above the table where it points you to information about the difference between the two. \$\endgroup\$ – Tom Carpenter Jan 28 '17 at 12:57
  • \$\begingroup\$ "For more information about the high-speed and low-speed I/O performance pins, refer to the respective device pin-out files.", followed by a link to all the pin-out files for each device. \$\endgroup\$ – Tom Carpenter Jan 28 '17 at 13:00
  • \$\begingroup\$ The device pin-out files detail which pin belongs to which group but do not go into detail on what the differences are \$\endgroup\$ – Arne Jan 28 '17 at 13:29
  • \$\begingroup\$ The table on p.34 seems to refer to differential signalling, however I'm looking for single-ended 3.3V LVCMOS. \$\endgroup\$ – Arne Jan 28 '17 at 13:32
