1.7.9. HPS I2C_EMAC and MDIO 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.

There are three sets of I2C_EMAC interfaces that can be used as I2C interfaces or as the MDIO pins for the EMACs. Please take note that the I2C_EMAC and MDIO modules must be used with the corresponding EMAC interfaces. For example, you can use either I2C_EMAC0_SDA and I2C_EMAC0_SCL or MDIO0_MDIO and MDIO0_MDC with EMAC0.

The I2C protocol requires pull-up resistors to VCCIO_HPS on both the serial data and serial clock signals for them to function correctly. The value of the pull-up resistor varies depending on your board loading, but it is typically 4.7-kΩ or lower.

Typically the MDIO pin requires an external pull-up resistor to VCCIO_HPS in the range of 1.0-kΩ to 4.7-kΩ.
