1.4.10. HPS I2C Pins

Note: Altera recommends that you create an Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software will check 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.

In addition to the three I2C_EMAC controllers, there are two additional I2C controllers (I2C0 and I2C1) for dedicated I2C usage in the Agilex™ 5 HPS.

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.
