MIPI I3C at embedded world 2026: What’s Next for 1.3

MIPI I3C was one of the more useful protocol discussions at embedded world 2026, because it sits right in that unglamorous but critical layer where sensors, controllers, memory, cameras, and system management all have to cooperate without turning a design into a pin-hungry mess. In this interview, Michele Scarlatella and Jonathan Georgino explain why the bus is moving beyond its original sensor niche and why engineers should pay attention now rather than waiting until it quietly becomes unavoidable.

What comes through clearly is that I3C is no longer just a neat successor to I²C for sensor links. As the current specification page and recent MIPI material show, the ecosystem now stretches into DDR5 sideband management, enterprise SSD control, camera control, debug and trace, and a broader class of embedded and mobile systems. That makes this less of a “future standard” story and more of a “check whether your roadmap has already been overtaken” story.
 

Why MIPI I3C Keeps Expanding

One reason MIPI I3C keeps gaining momentum is that it attacks several old annoyances at once. It reduces pin count, supports in-band interrupts, keeps coexistence with legacy I²C devices, and offers a large speed jump over classic I²C. MIPI currently cites typical transfer rates of 11.1 Mbps, with higher data-rate modes reaching 100 Mbps. That is a meaningful step up for designers trying to juggle low power, tighter board space, and more intelligent peripherals in the same product.

The interview also does a good job of showing why this matters for Edge AI hardware. If your product depends on more sensors, smarter local processing, and battery-conscious design, the plumbing starts to matter a lot. Low-power cameras, MEMS devices, and wearables are obvious examples, but the same logic applies to industrial and embedded systems that need cleaner control paths and fewer legacy workarounds. If you want a refresher on the protocol itself, our earlier webinar coverage is still a useful starting point.

MIPI I3C 1.3 and the Practical Next Step

The most forward-looking part of the discussion is the preview of I3C 1.3. The headline themes are better data integrity, longer cable reach, more devices on the bus, and bridge technology for bringing older interfaces such as I²C, SPI, and GPIO into the fold. That last point may end up being especially important in the real world, because very few engineers get to design from a clean sheet while angels sing softly over the schematic.

MIPI has also been making adoption easier around the edges, with publicly available I3C Basic material, application notes, host-controller support, and test resources. So this is not just a standards-body promise floating in a PDF somewhere. The surrounding tooling is becoming more serious, and that is usually when a specification starts moving from conference slide to shipping hardware.

For engineers working on sensors, wearables, embedded controllers, or compact AI-enabled devices, this interview is worth a watch. It is a grounded look at where the bus stands now, where it appears to be headed next, and why an interface standard can suddenly become very interesting once it starts saving board space, power budget, and engineering patience all at once.
