I3C Cafe - Now Brewing: A New Digital Protocol

Welcome to I3C Cafe, the first site dedicated to the exchange of news and information regarding industry adoption of the MIPI I3C® (and subsequently I3C BasicSM) protocol. First released in December 2018, the MIPI Improved Integrated Inter Integrated Circuit (I3C) communication protocol has matured to the point that it's starting to show up in mainstream semiconductors. No longer constrained to FPGA projects with licensed IP blocks, the stage is set for widespread adoption. Sit back, sip your coffee and enjoy the show!

With I3C being the standard for DDR5 management, it only makes sense that the ecosystem of supporting components also adopt I3C as their primary communication interface.

NXP RT500 & RT600 Crossover MCUs Enable I3C Development Today

Published on Jan 27, 2022

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

Published on Jan 27, 2022

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

Published on Jan 27, 2022

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.
