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.
