alt Hacker News> But also: Cortex A35 is from 2015!
The pipeline from new ARM cores to shipping silicon is surprisingly long. Cortex-M85 was announced in 2022, and there's still almost nothing on the market that implements it.

Renesas uses them, but the Renesas MCUs are quite expensive, even if they seem to be the best.
So if you are willing to pay a high price, which might not be worthwhile, it is not difficult to find MCUs or development systems with Cortex-M85.
I don't think it's merely long pipeline. Simpler explanation is that there is just not much demand for these middle-class cores; A55 cores are from same generation and started appearing in socs pretty quickly. I suspect that the benefits of A3x (compared to A5x) just werent there for vendors to justify adding them to their portfolios
