It's surprisingly difficult to search for devices which support I3C. In many cases, it's buried in the details of the product pages or datasheets. You may be able to find a product announcement that mentions it, but that's not always the case. As such, we're actively maintaining a list of the I3C devices we find on the market on this page.
The devices in the table below feature I3C Controller support. These processors and microcontrollers are very likely able to operate as I3C Target devices as well.

The new Entry Line RA-series MCUs support I3C SDR communications in Controller or Target roles. Still no HDR-DDR mode, but offers a great step up from the limitations of the RA2E2.
After years of having I3C Target support in their sensor lines, ST has finally added an I3C controller to their catalog with the introduction of STM32H5 series MCUs.
Marking their first formal participation at the Embedded World conference, The MIPI Alliance is offering an I3C session as part of the Board Level Hardware Engineering track.
