Hi,

Just wondering if anyone has any comments on National's COP8, CompactRisc
and CP3000 processors?

Their primary focus seems to be on the analog components now but the flash
micros are still readily available.

Any hope for a revival of new parts and a future for their micros?

regards,

John Strupat

and CP3000 processors?

On the COP8 front, I think these products are in maintenance mode. I
haven't seen any new product announcements, and I don't think they're
seeking new customers. The development tools (ICEs) are discontinued,
also. Metalink gave all the source for the host-side tools to NS, and
now NS maintains it. I don't think you can buy the hardware any more.

The situation when I left National in 1998 was that
National management did not allow the microcontroller group
to do standard CR16 mictrocontrollers, only ASSPs, idally
only sold to a single customer.

The applications people told management, that the original CR16
(with the CAN controller) was an Airbag controller ASSP and thus
they were allowed to design a general purpose micro.

The CR16 design team resided in Herzlia in Tel Aviv
and I think this design centre was sold to AMD.

The CR16 could have been a success if it was designed
inside a company which had a clue about the microcontroller market.

I think it has little future at this time.

Yes, and when they spun off the 32-bit CPU business, their margins
improved, and that left the uC in rather no-mans land.
Thus you have an Analog mindset company, doing well in analog, so the
digital section will not have a great future...
The CP3000 look to have more of a niche, as they are a CPU second,
and communications devices first.

Ulf, do you know what happened to the GCC port of the CR16? IIRC they
were planning to release it for inclusion in the official GCC
distribution but that never happened. I exchanged several emails with
people there at Tel Aviv and they were very purposive about the CR16.

CR16 is a nice architecture but support was -> 0. I guess HCS12, M16C
or even MSP430 dominate that niche now.

No, I do not think AMD would want them to do spend any time on this.

And maybe soon to be replaced by ARMs...
