I just discovered these new LPC 32-bit processors.

http://www.nxp.com/news/press-releases/2011/10/nxp-cortex-m0-microcontrollers-in-high-volume-tssop-and-so-packages-target-8-16-bit-applications.html

It seems that they are available in a DIP 28 package (albeit I heard in a .6" pitch I think which would be stupid). Personally I don't care about DIP but it would be good for prototyping.

Some time back I said that if NXP ever made the LPCs in a smaller package I may never use an AVR again. Maybe that time is approaching faster than I thought.

Yeah the 0.6" pitch is a bit stupid, 0.3" would be better. There is still no word as to when they'll go in to production.

Also, Microchip have released their PIC32 in a 28-pin 0.3" package so there's exciting times ahead for your breadboard :-)

There's only 3 things wrong with that, 'P', 'I' and 'C' smiley

It's interesting that this (ie DIP packaging for new chips) is happening at all, maybe it's to hook the non-professionals and students so they start specing the family of uC they are used to when they get a job.

I would have thought though that any company buying enough chips to make a difference would either always use the same family or use whatever was best regardless of the family. Either way the existence of a DIP would be neither here nor there.

And surely they don't care about the hobbyist.

From my own POV I like the TSSOP20 version, that's a lot of punch in a tiny package.

Hi Rob,

I discovered your site through this post, incredible.

Can you tell me what's wrong with PIC (and not with Atmel) ? Some other voices in another forum said that ARM was the only one really reasonable because second sourcable, but I think that's not really true since every manufacturer makes its own derivative. So I'd like to hear your opinion/arguments.

I wanted to migrate from 8-bit to 32 bits, and looked at PIC32-pinguno and STM32-maple, but the IDE doesn't look stable and complete enough to me, and I don't consider having the right skills at that level. Since the Due seems vaporware, this leaves me stuck to 8-bit Atmels.

Thanks, it keeps me off the streets.

Well for one I hate the sans-serif font they use in the data sheets smiley

The short answer is that in general it's six of one half a dozen of the other. My personal bias goes way back to the first PICs, they were terrible with no stack and a stupid bank-switched architecture IIRC and I have trouble getting past that. But I see no reason to choose one brand over another these days, just look at the features of the chips, the dev boards and the support.

Yep, unless you are dicking around at a low level it doesn't help, as you say all vendors have their own IO and that's what most people play with. Obviously any ASM will be portable. AFAIK none of the chips have second sources.

I've been spending a lot of time looking at the LPC chips, they seem really good with cheap ($29) dev boards etc. The LPCxpesso forum is quite good as well (but nothing like the support you get here). That's one reason I'm holding off on a 32-bit decision until the Due arrives, but I don't think I'll hold off much longer if there's no more details forthcoming. All we've seen so far is an erroneous feature list and a PCB photo that could almost be a Mega.

Where do you base this on?
There is no indication that it is not coming out, they are probably testing it at the moment.
A new product takes time to develop, saying it is vaporware in this stage is totally overreacting
