Electrical specification?

[gmonroe]

Good morning,

I'm working on a design using the NANO54415. However, I can't seem to find any sort of electrical information on the module. The only specification I can find looks like marketing material. Is there any sort of electrical specification available that includes voltage and timing information, maybe even schematic snippets for various interfaces? As a fallback I would accept a schematic and work back from there.

Thanks in advance,
Glenn

... I'm not sure what you're looking for when you ask about voltage and timing information. It's a 3.3V part. The I/O pins are directly connected to the Coldfire processor on board, so that's the stay within that part's specs. As for timing, I really have no idea what you're after...

[gmonroe]

For any given IO or interface on a board there is the nominal voltage that it operates at (in this case 3.3V) then there is the actual range that is acceptable for an input or possible with an output (e.g. 2.7V-3.6V). These show up as Vih, Vil, Voh and Vol in the spec. In order to design a product that will work I need to know what range of output voltages are possible and what range of input voltages are acceptable. In other words I can't always just connect a 3.3V nominal interface to a 3.3V nominal interface and accept that all is well. For timing information I need anything related to setup and hold as well as any necessary rise/fall requirements, etc.

This information should be easy enough to find in the processor spec. However, without a schematic for the module I can guess what the connections will be, but I won't know for certain.

Thanks,
Glenn

Hi Glenn,

The specs for all the h/w are in the \nburn\docs\FreescaleManuals section. The datasheet for the 54415 processor is there will all the electrical specs. What I do is use the netburner data sheet, which shows the bga ball numbers, and reference them to the freescale spec. That will give you an exact match. Not all the pins are the same. And I think there is some freescale errata that says originally the a/d pins could be used as GPIO, but in reality they can not.

Newb here,

That sounds like what I'm looking for, but where can I find \nburn\docs\FreescaleManuals?

I had assumed you purchased a development kit. Do you have one?

If not, lets look at this the other way around. Exactly what electrical specifications do you require for your project? What are you connecting to, voltage levels, current requirements, impedance, etc.

[gmonroe]

We do have the development kit. It took me a while to track down the CD to get into that directory. However, that directory just has Freescale chip-level documentation. Is there a way to get the schematic for the NANO 54415 in order to verify my design? After another 30 minutes or so of searching I still don't see it in that whole directory structure.

Hi,

Its in my dir structure, so I'm not sure why its not in yours. I would contact netburner support directly.

If you don't have your own set of specs for what your connecting to, how will the electrical specs of the module be of any use?
