Are there any impending MIPI I3C fixes/errata that should be applied now?

Note: With the release of I3C v1.1, this question has been deprecated, but it is left here for reference. For example, see question below for what’s new in I3C v1.1.

Based on learning from the early implementations, I3C Interoperability Workshops, queries from adopters, and reviews by the I3C WG, this FAQ represents clarifications, planned improvements that can be implemented by I3C v1.0 Devices, and other hints about what’s coming next.

What future MIPI specifications will be leveraging I3C?

Many other MIPI Alliance Working Groups are in the process of leveraging the I3C Specification. As of the writing of this FAQ, the list includes:

  • Camera WG: Camera Control Interface (CCI) chapter of the MIPI Specification for Camera Serial Interface 2 (CSI-2), v4.0 [MIPI06] (In development)
  • Debug WG: MIPI Specification for Debug for I3C, v1.0 [MIPI07] (In development)
  • RIO WG (Reduced I/O): MIPI Specification for Virtual GPIO Interface (VGISM), v1.0 [MIPI08], reducing number of GPIOs used via I3C (In development)
