revise my design please!

Discussion created by Francois Rainville on May 6, 2009

Hi everybody,

 

My name is François and I am new to freescale controllers. I already played a bit with my Softec starter kit but now I would like to do my owm design.

 

I have experience with PIC microcontroller and I had a course on "HCS12" but we used a development board and learnt only software design.

 

I use Altium designer to design my boards

I Would like to use S12XDP512 for different reasons

 

for now, I have no specific application, I just want to get the controller working on a board I have designed.

 

I made a small design in altium designer and I would like to have advices from professionals who have more experience than me with these controllers before going too far in design and do something that don't work.

 

I followed the pcb recommendations on the datasheet and I wonder if these recommendations are overkill or if this is not done properly, the controller just won't work.

 

I also based my design on the schematics from a development kit.

 

Here is my circuit design.

Sorry for the size of the pictures... see the copies in attachments

 

So please fells free to give me any advices about my design, would this work ? could it be better or simpler ?

 

Thank you very much

 

I attach my Altium project and library if you want to take a closer look.
