What is I3C®?

In this video, learn about the I3C® protocol, and how it compares to I2C. I3C is a new serial protocol from the MIPI® Alliance that improves upon I2C with higher clock speeds, dynamic addressing, in-band interrupts, and many other new and exciting features!

Microchip out here dropping news on I2C’s sequel like we wouldn’t notice.
I’m excited to try I3C out!

So I2C is written I2C but prounounced Eye Squared See, whereas I3C is written I3C and pronounced Eye Three See not Eye Cubed See?! Totally makey sensey

[portblock]

Seam like too much of a squeezing in more features to only have something slightly better. I believe (I could be wrong) I2C was for inter board coms. To me, if my application/design needs more speed then SPI or UART, If I need to go off board then CAN or Ethernet

[Monster-iwcu]

Hypothetically I got a CM5 module from RasPi; is there a world I ever use this? Seems like this is only going to really be usable between microchip products, which severely handicaps its usefulness.

This sounds an awful lot as a solution looking for a problem? If I²C doesn't cut it, I'd go for CAN, USB or Ethernet... I'm having a hard time placing I³C in this picture, especially when device support is pretty non-existent at the moment and established alternatives are available aplenty.

I feel I learned very little. For instance, apparently arbitration is done at low speed, though that wasn't explicitly stated, then it would seem the only speed benefit would be for long packets.

Always check the Hardware Errata.
PIC18-Q20 Family,
* I2C = 8 Hardware issues
* I3C = 22 Hardware issues

[jensschroder]

then I can connect it to the I2C bus, fine
