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.
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
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
I2C is supposed to be written and pronounced I-squared-C or IIC which stands for Inter-Integrated-Circuit. So it is supposed to be intra-, not inter- board, i.e. between chips on the same board. Not sure if anyone has contrived a rationale for I3C yet though! The address assignment looks like a killer feature since at the moment you have to hope that two ICs will not have the same default addresses or else IC pins have to be reserved for selecting amongst a limited number of alternative addresses.
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.
Hi there, thanks for reaching out! That would be the PIC18-Q20 Product Family, as Max noted previously. These MCUs are equipped with I3C® modules. The link he sent is perfect: www.microchip.com/en-us/products/microcontrollers-and-microprocessors/8-bit-mcus/pic-mcus/pic18-q20
Microchip out here dropping news on I2C’s sequel like we wouldn’t notice.
I’m excited to try I3C out!

Design marvel in electronic spheres 👍

@@john_hind Thank you for the correction, i get intra and inter mixed up all the time, but yes, I agree with what you say
Always check the Hardware Errata.
PIC18-Q20 Family,
* I2C = 8 Hardware issues
* I3C = 22 Hardware issues

Morphing into CAN bus?
Pretty much, but primarily pretending SMBus (with e.g. host notify and address resolution) doesn't exist.
then I can connect it to the I2C bus, fine
Eye Cubed See
which mcu supports this protocol?✅️
