Re: Do you see any future to the 8-bit MCU's?

Hi,

During the latest months I have been receiving offers for 32-bit MCU's, mostly based on ARM-Cortex CPU's, at prices I'm currently paying for 8-bit devices, or even cheaper! This has brought me to benchmark them with the MCU independent part of my C++ code and surprisingly the results are quite similar.

Same price, same flash consumption ... what do yo think? Is this the end of the 8-bit's? I guess it is.

I just redesigned an old card using a 8051, an A/D converter,
a static RAM (2 kilobytes) and some glue logic. The new card
was done with a Stellaris Cortex, LM3S818. All the IC:s on
the new card costed together less than the A/D converter
chip on the old design.

When our current AVR -based designs need to be replaced, the
Stellaris chips are the potential replacements.

The Stellaris chips run fast with minimal electricity,
but there is the price of a quite complicated set-up of
the master and peripheral clocks and port pins.
