112 or 144 pin versions of the XDP, will it work?

Post by davebmw »

Is there any reason you can think of that we are not using the full blown 144 pin LQFP with all the extra pins?
I know that the development board featuring the 112 pin LQFP s12xdp512 is an easier solution because its an available module. but PCB costs aside is there a reason we are not considering it.

Main reason i ask is i have 2 samples of each on their way from Freescale and i intend to get PCB's made for the full blown version as well as the 112 package.

I don't know what i will want to do with the extra IO channels but i hate limits!

No reason at all, it will work just fine and not use the extra pins till you write code for it. I can patch some of it to work that way if you are going to use it and it shouldn't affect anyone else at all.

8 of the extra pins are ADC pins and very useful :-) Other than that the increase isn't all that useful really, but the more pins the merrier :-)

I moved the thread/post here because it's core stuff really.

I look forward to seeing your progress! :-)
