In early 2022, I shared my excitement regarding news of Microchip's I3C Target-Only implementation in the 8-bit PIC18-Q20. Now I'm please to let you know that it's publicly-available. But that's not all -- it's available as a Curiosity Nano development board, making it one of the lowest cost, lowest effort paths to developing your own I3C Target device.
This device has some really clever features, particularly in regards to it's implementation of power domains to have a very low voltage level supported for the I3C bus. It's very well suited for I3C-to-x bridge applications as well. The Curiosity Nano dev board (shown above) is available for purchase for ~$24 directly from Microchip or from Mouser.
But wait, there's more...
Microchip has partenered with Binho to provide everyone who purchases the PIC18-Q20 Curiosity Nano development kit a free 45-day license to use our I3C Basic Protocol Analyzer Plugin for Saleae Logic. This makes getting up and running with this MCU for I3C applications quick and easy. All you have to do is order your dev kit from the links above and then submit this form and you'll receive immediate access to the plugin files and license key.
Finally, if you're in search for an I3C Controller to use while developing your PIC18-Q20-based I3C Target, might I suggest taking a look at our brand-new USB to I3C Host Adapter, the Binho Supernova.

Headlining as the industry's first Cortex-M85 core, this device contains another industry first, details of which are buried a thousand pages deep within the User's Manual
Microchip's 8-bit MCU offers the fastest path to I3C Target development, especially when paired with Binho tools.
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.
