1.4.11. HPS I3C 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 two I3C controllers (I3C0 and I3C1) for dedicated I3C usage in the Agilex™ 5 HPS.

The I3C 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. Altera recommends using a 1 kΩ pull-up resistor. Refer to the I3C Controller Design Guidelines and Examples section in the Hard Processor System Technical Reference Manual: Agilex™ 5 SoCs for more information on design guidelines.
