Pin voltage must not exceed VCCIO_HPS .

  • Pin voltage must not exceed VCCIO_HPS .
  • All pins are in undetermined state.
All pins are configured as Schmitt Trigger input with 20 kΩ weak pull-up enabled. All pins are configured as Schmitt Trigger input with 20 kΩ weak pull-up enabled. Valid data transactions can be initiated.
  • Pin voltage must not exceed VCCIO_HPS .
  • All pins are in undetermined state.
Note: After the Agilex™ 7 device fully powers up, the voltage levels for the HPS I/O pins must not exceed the DC input voltage (VI) value or the AC maximum allowed overshoot during transitions.
