i bought this motorola IC and i want to work it out today, it has the exact same physical and digital dimensions (no. pins) as an ATmega328 as in the uno unit. can i stick it in and use a USBasp to check and see if its AVR programmable? ie im not going to wreck the uno or IC by doing so? i cant find a datasheet for it.
Errr. I would not do that without a data sheet that said it was completely compatible.
There are hundreds of ICs with the same number of pins. Assuming that they are identical just because they have 28 pins makes no sense.
Cats and alligators have four legs. They are quite different otherwise.
ATmega328 is a proprietary device produced by Atmel. Motorola is a competitor. While not impossible, it's highly unlikely that Atmel would allow Motorola to make identical chips.
What Motorola chip did you buy?

your subject line does not describe anything useful
you used "this motorola IC" ........
no name, no photo, no link........
you bought something..... the subject line refers to a shoe,
you could at least post a link to what you bought.
basically, the answer is NO.
you cannot go around replacing electronical parts with shoes
and you cannot swap out two parts because they have the same footprint.
also, your post says it does not have pins, so how are you going to swap out the ATmega328 ?
a friendly word of advice, never use pronouns. never assume,
there is no "...as in the uno unit" there is the UNO or there is not,
our general answer to this type of question is that if you have to ask, you probably are not able to make it work.
often people will ask "what were the results that you found when you actually tired?"

my dining room table has four legs.
Well said Dave, I was starting to say much the same as what you have said, even about (no. pins).
I decided after 15 seconds of typing to just abort and leave it alone.

Precisely!
This really is a humour post.
Even the subject line premise is wrong - you have to try the shoe on first to understand whether it fits.

Are you sure it's not in fact an alligator?
yes yes i know the logic isnt there hence the title joke i was just curious as to what a program like AVRDudess 2.2 would respond to connecting it via a programmer and seeing what it detects it as. its a signal control chip, dsPIC30F2010 ill look for a data sheet again.
No alligators where arduidiot lives, maybe a lost or migrating crocodile heading south.
dnt worry about i found the datasheet lol its like a part of me likes to give you people ammunition
Ah, it's a PIC chip, yep sure plug it in. But first, cut all the tracks on the PCB and re-route to the correct pins, after reading the datasheet. Even then, we want to see smoke from over the other side of Oz.

I found the datasheet
You looked, eh?

consider your post as a Christmas present to that side of us that like to shoot the ducks.
i bought this motorola IC
wow, when did Motorola buy out Microchip ?
I guess by now, you have surmised that a PIC and an Atmel chip are not comparable.
think 4 legs... the PIC is a dog, the Atmel is a table.
I am no expert, but it seems that back in the old days, the best introductory chip was the BasicStamp. the PIC was a sheer wall learning curve and you had to buy C software for a couple hundred dollars. or learn Assembly.
Atmel came along with the Butterfly and showed that for $20 you can put a lot of stuff on a small form factor.
someone came up with the idea of a bootloader ala BasicStamp, put it on the much friendlier chip by Atmel and then gave away the software.
now, the masses gravitate to the Atmel chips because of the Arduino and the schools teach with the Arduino. Even though the underlying chip is much more powerful, even served up with the arduino overhead, it can to wonders.
not sure why the folks over at Microchip have not leapfrogged and offered their own board and free programming software. (and fixed the kooky memory allocations) and offer a simple learning tool that would have broad appeal. I wonder if they see market share falling as the broader base of new engineers use the more familiar and easier to use Atmel chips ?
Do you think that Arduino enthusiasts are a significant market compared to the totality of embedded systems using similar microcontrollers?
dave-in-nj:

I'm sure I actually have one of those. I wonder where it is?

Easy "PICk" between those. Mind you, I'm with Steve Gibson on that.
Just looked myself up on PIClist - haven't been there for 15 years!
Don't bother looking me up, you won't find me on such a PICky list.
I used Motorola 68HC811 prior to Atmel, with other Motorola before that and then a long stint with Zilog Z80, beginning my days with Signetics 2650. 8)

ok fine but i had no datasheet for it but i had one for all the others i bought that day so yea i dont really have a follow up statement prepared
