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.
