3 V Compatible I/O Pins

Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.

Note: The I/O pins are tri-stated with a weak pull-up during power up.
Pin Name ( Stratix® 10 Devices) Pin Name ( Stratix® 10 GX 10M Device) Pin Functions Pin Description Connection Guidelines
IO3V[0,1,2,3,4,5,6,7]_[10,12,20,22] T[1,2,3,4]_IO3V[0,1,2,3,4,5,6,7] I/O

These are the 3.0 V I/O pins. Each H- or L- transceiver tile supports eight 3.0 V I/O pins. These pins support 1.2 V, 1.25 V, 1.35 V, 1.5 V, 1.8 V, 2.5 V, and 3.0 V I/O standards.

For details about the supported I/O standards, refer to the Stratix® 10 Device Datasheet .

Connect these pins according to the I/O interface standard you are using. You must provide power to the VCCR_GXB, VCCT_GXB, and VCCH_GXB pins of a transceiver tile to enable the 3.0 V I/O pins within that tile. For any transceiver tiles that have their VCCR_GXB, VCCT_GXB, and VCCH_GXB unpowered, the corresponding 3.0 V I/O pins within that tile is disabled.

Using 3 V I/O pins from an unpowered tile can potentially result in configuration failures.

Connect unused pins as defined in the Quartus® Prime software.
