5.7.3. Guideline: Do Not Drive I/O Pins During Power Sequencing

The Intel® Cyclone® 10 GX I/O buffers are powered by VCC, VCCPT, and VCCIO.

Because the Intel® Cyclone® 10 GX devices do not support hot socketing, do not drive the I/O pins externally during power up and power down. Adhere to this guideline to:

  • Avoid excess I/O pin current:
    • Excess I/O pin current affects the device's lifetime and reliability.
    • Excess current on the 3 V I/O pins can damage the Intel® Cyclone® 10 GX device.
  • Achieve minimum current draw and avoid I/O glitch during power up or power down.
