I3C Cafe - Now Brewing: A New Digital Protocol

I3C Devices

Updated on Aug 06, 2022

It's surprisingly difficult to search for devices which support I3C. In many cases, it's buried in the details of the product pages or datasheets. You may be able to find a product announcement that mentions it, but that's not always the case. As such, we're actively maintaining a list of the I3C devices we find on the market on this page.

I3C Controllers

The devices in the table below feature I3C Controller support. These processors and microcontrollers are very likely able to operate as I3C Target devices as well.

NXP RT500 & RT600 Crossover MCUs Enable I3C Development Today

Jan 27, 2022 Max Peck

The iMX RT Crossover Microcontrollers are an interesting beast. They've got some interesting bells and whisltes, but the real reason that I'm writing about them today is due to the fact that the RT500 and RT600 series devices feature I3C peripherals.

Diodes Inc. Announces High-Speed I3C 1:2 Mux

Jan 27, 2022 Max Peck

Aside from I3C-capable Controllers and Targets, another category of devices that are imperative for successful and wide-spread industry adoption of the I3C protocol are interface devices such as switches/muxes, buffers/level-shifters, etc. Diodes Inc. recently announced[pdf] their first I3C interface device, the PI3CSW12, a 1:2 Mux/DeMux with Output Enable control signal.

STMicro Sensors with I3C Support Available Now

Jan 27, 2022 Max Peck

While we're eagerly awaiting STMicro to introduce their first micronctroller which features an I3C peripheral, their MEMS sensors team has already launched several devices to mass production. This gives me even more hope that their first micrcontroller with I3C support is just barely over the horizon.
