5.5.3.2. Programmable Output Slew Rate Control

The programmable output slew rate control in the output buffer of each regular- and dual-function I/O pin allows you to configure the following:

  • Fast slew rate—provides high-speed transitions for high-performance systems.
  • Slow slew rate—reduces system noise and crosstalk but adds a nominal delay to the rising and falling edges.

You can specify the slew rate on a pin-by-pin basis because each I/O pin contains a slew rate control.

Note: Intel recommends that you perform IBIS or SPICE simulations to determine the best slew rate setting for your specific application.
