A new 80C51 core, Industrial/Automotive small package
TSSOP16 and up, from Infineon.

XC82x data is rather well hidden on the Infineon website, more info is
also in the 133MB Tools download.

WOW, I started with the 8031 in 1982 !!

I guess you can teach an old dog new tricks :-D.

Thanks

oh there are plenty of very modern MCU's based on 8051 core

This is true.

I have found the SiLabs to be expensive for parts they have.

The speed is nice, but not enough to not use more modern CPUs.

Two companies I have worked for in the last few years used SiLabs parts.

When I asked why they still used 8051 architecture they said they did
not want to spend the time learning anything new.

I found that reasoning to be very short sighted.

But, to be adding new 8051 chips on the market must mean there is still
need for it.

Maybe I'll put 8051 back on my resume and see what happens. :-)

yes, because they work well.

hehe - Now that _is_ bizarre logic. I trust you are NOT
writing that on an X86 PC!!!! It would be very short-sighted of you,
to still be using that core.
(or Arm, as that too, is an old lineage!)

Look at the Cypress PSoC3.

Of course. The 80C51 is still the most-shipped core in the world.
There are truckloads of Asian variants (license free, and good
tools).
Only when your project goes above a certain size, does it make sense
to look at something else.
