Headlining as the industry's first Cortex-M85 core, this device contains another industry first, details of which are buried a thousand pages deep within the User's Manual
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!

Microchip's 8-bit MCU offers the fastest path to I3C Target development, especially when paired with Binho tools.
The new Entry Line RA-series MCUs support I3C SDR communications in Controller or Target roles. Still no HDR-DDR mode, but offers a great step up from the limitations of the RA2E2.
After years of having I3C Target support in their sensor lines, ST has finally added an I3C controller to their catalog with the introduction of STM32H5 series MCUs.
Marking their first formal participation at the Embedded World conference, The MIPI Alliance is offering an I3C session as part of the Board Level Hardware Engineering track.
Many folks are about to have easy access to an I3C-capable MCU thanks to Espressif's next-gen ESP32 SoC
The MIPI Debug Working Group is planning to host a Debug for I3C Interop Workshop at the Member Meeting in June 2023. Fill out the interest form if you'd like to participate - it's definitely worthwhile!
We're sharing our findings after spending some time building a new automated I3C test bench using the SC4420 by Signal Craft Technology.
The portfolio contains 4 different device series, one of them being described as containing a "broad range of peripherals". We stopped at NXP's booth at Embedded World to learn more.
Ladyada and PT produced an amazingly concise explanation of the key concepts of I3C in just ~12 minutes.
TI has a hidden gem buried in their catalog of devices: an I3C Switch and Voltage-Level translator.
Proactive standardization of a USB-to-I3C Bridge paves the way for a cohesive I3C ecosystem without the quirks of manufacturer-specific implementations.
NXP acknowledges upcoming I3C-capable line of temperature sensors and make their I3C products easier to find. Kudos to their marketing team!
Employment of I3C Basic for the link layer of ETSI SSP paves the way for exciting new embedded system security features.
MIPI Alliance hosted their first I3C Interop Workshop open to non-members. By all measures, the event was a great success, and let me tell you why.
The result of a close collaboration with Intel, Renesas unveils a family of 2:4 and 2:8 I3C Intelligent Switches to greatly improve scalability of I3C on next-gen servers and infrastructure equipment.
The MIPI Alliance will be hosting the next I3C Interop Workshop on 13-14 June in Munich, Germany. This workshop will be open to non-members for the first time!
The Renesas F0443 is a Dual Matched Broadband RF digital variable gain amplifier designed for use in diversity/MIMO receivers. This is quite a deviation from the typical applications of I3C-capable devices.
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.
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.
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.
Bosch Sensortec released the BMI263, a 6-Axis IMU, their first I3C compatible device, well over a year ago. They are keen to point out support for I3C all over their product page and marketing materials for the device, unlike some who are somewhat silently adding supporting for I3C. However...
TDK InvenSense, leaders in the MEMS IMU device category, have already introduced I3C support in several of their devices. Just like IMUs from STMicro, TDK InvenSense took the approach of supporting SPI, I2C, and I3C protocols on their devices, but with a key differentiator...
Microchip recently posted a product brief to their website with little fanfare introducing a new family of PIC18 devices which will be their first to include I3C support.
