BRIAN- you are right about enigneering time being short. and people dont
mind $20 instead of $5.
I usually consider that I need 2x the clock and 1.5x the memory and 1.5x
the program memory for development.
At least. the code needs to be able to run with 90% of it with
optimization off, big buffers for traces...
The RX1020 though at 500 MHz, is a significant step from a even an H7.
and all the RAM in the 1020 is TCM.
But a redesign is a redesign the board would change anyway. I am happy
to cad something up and hand over for someone to make...
so everything is usually prototyped on a PC , mindful of the limits of
the micro..
What I'd like to see is a processor like the A5 with NEON. The NEON core
is the ticket. None of those processors are QFP, and they usually
require DRAM. Some have enough internal on chip memory for our
applications (say 256 kbytes) not to need external DRAM, and to some
degree we can run XIP from quad spi flash with good cache.
Nevertheless, the 600 MHz RT processor clock speed is getting up
there... and the series will go to 800 MHz in time.

The most-limited resource is engineering time by people on this list.
Some people here build and integrate their own electric vehicle, too,
but everybody here doesn't.
Would you rather have a $100 item in months, or a $25 item never
because it requires code redesign for space-saving plus circuit board
design and fabrication?
