@azonenberg@ioc.exchange Some newer STM32s (some parts of the U5 series for sure) have multiple I/O voltage domains, similar to FPGAs
They only have M33 not M55 cores, but they are plenty powerful (both ICACHE/DCACHE and pretty high 160 MHz clock)
Their bigger family members seems to be the H5 series, maybe check out those too

@helaslo@mastodon.social The H5/U5 is waaay too slow, I'd ideally want like a GHz M7. The V8 series seems attractive to me, but doesn't seem to be general availability yet. They're probably all going into starlinks or something
