Re: 8051 dead or what?

What about a soft core 8051 written in VHDL or Verilog? Reusable in an FPGA
for a long time to come. :-)

Lets face it the 8051 will carry on for a long while yet. There are
VERY many producers of 8051 parts and cores, never mind a second source
you have multiple. The 8051 core is low cost if you want to put it in an
FPGA to create your own.

There are many high quality tools and a lot of experience for the 8051
out there. The packages range from 8 pin SMT to 150+ pins though I
think the 40 pin DILs are hard to find now... Even radiation hardened
versions.

I am sure that the 600 odd variants will shrink down to only a few
hundred over time but I can't see it dying out for a few years yet. I
think it is the most popular MCU on the planet including x86. AFAIK most
PC's have one or two 51's in them somewhere. Used to be keyboard and
mouse.

Hi All.
I used Atmel 8051 derivatives in all my earlier projects. Atmel made a
really nice chip in the AT89C55 then later they changed the die and it
was not as good; chip 'engineers' come along and change a tried and true
chip and its specs change and then it does not work properly anymore. EG
CD40106/74C14 performs totally differently than the original National
Semiconductors CD40106.
But thats not the subject of this post ;-)

.....................

I have noticed that in my latest suppliers linecard that only the
AT89c2051 is being sold and it seems the 'old' 8051 is a dying breed.
Even to source the AT89C55WD is a special order here in New Zealand.
Does this mean the 8051/2 series is considered defunct? Should I be
looking at alternatives for my next product? If so, its a pain as I have
programmer, emulator and software to achieve my goals with the 8051
series.
Thank you.
Alistair.
