We have an industrial controller which uses an 80C32 cpu. The
controller has been in production for many many years and is very
reliable. Intel has announced that they won't make these chips after
next year. Does anyone have a simple suggestion how to just continue
with this controller design or is it going to require a re-design with
new technology?
Thanks in advance for your opinions and advice.

You really should have *cross-posted* this question to all the relevant groups
so that the answers could be seen by all.

For the benefit of posters here - the 80C31/2 series is highly 'second-sourced'
and in any event Intel don't even sell very many of them anymore.

Good second sources are typically Philips and Atmel. MHS and OKI also used to
make them ( amongst others ) and many variants are available from multiple
vendors including versions with faster clocks and faster machine cycles.

It's estimated that the 8031 family of MCUs represents 50% of all MCUs sold
worldwide last time I checked.
