2.3.2.7. PCI Clamp Diode

The MAX® 10 devices are equipped with optional PCI clamp diode that you can enable for the input and output of each I/O pin. You can use this diode to protect I/O pins during voltage overshoot.

The PCI clamp diode is available in the Quartus® Prime software for the following I/O standards:

  • 3.3 V LVTTL/3.3 V LVCMOS
  • 3.0 V LVTTL/3.0 V LVCMOS
  • 2.5 V LVTTL/2.5 V LVCMOS
  • 3.0 V PCI
  • 3.3 V Schmitt Trigger
  • 2.5 V Schmitt Trigger

Dual-purpose configuration pins support the diode in user mode if you do not use the pins as configuration pins for the selected configuration scheme. The dedicated configuration pins do not support the on-chip diode.
