I3C Cafe - Now Brewing: A New Digital Protocol

Renesas Releases an RF VGA with I3C Control Interface

Published on Apr 30, 2022

I was looking through Renesas's portfolio and stumbled on an I3C device that somewhat bucks the trend (in a good way). 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. Up to now, most I3C Target devices have been either (a) sensors for use in mobile phones and tablets, or (b) related to the implementation and management of DDR5 DIMMs.

All the tech specs and datasheet can be found on the product page. I personally do not have an adequate technical background in RF to understand the nuances of this device and it's potential usecases, but I find it very interesting to see I3C support ending up in an RF amplifier this early in the industry-adoption phase.

Have a good understanding of how this device will be used and why I3C is useful /  relevant to it's success? I'd love to hear from you!

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.

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.

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.
