> MCU-class footprint (fits in 16 MB RAM)

That is absolutely not an MCU class footprint. Anything with an "M" when talking about memory isn't really an MCU. For evidence I cite the ST page on all their micros: https://www.st.com/en/microcontrollers-microprocessors/stm32...

Only the very very high performance ones are >1MB of RAM.

RAM on MCUs is getting cheaper by the minute.

A couple of years ago it was measured in bytes. Before the RP2040 is was measured in dozens of KiB now it's measured in MiB

While I agree that 16 MiB is on the larger side for now, it will only be a couple of years for mainstream MCUs having that amount on board

Also curious what MCUs you're working with to give you this impression?

RP2040 is 264k, RP2350 is 520k.

I use NXP's rt1060 and rt1170 for work, and they have 1M and 2M respectively, still quite far away from 16M and those are quite beefy running at 500MHz - 1GHz.

While I generally agree with you, the RT106x line does support external SDRAM as well. I've got an MIMXRT1060-EVKB sitting here on my desk that has 32MB of SDRAM alongside the on-die 1MB of SRAM.
