Hi guys
I was working on LPC11E14 when I realised that there are no Eagle CAD files
available for LPC11E14.
I wrote to NXP and they told me that they do not have the CAD files for the
same. I do not understand why would they produce a component and not
provide its CAD files, given that is one of the critical support work to be
done with the device.
Does anybody have any 3rd party CAD files for the same. It would be really
great of somebody could refer them.

Hi Shashank
one question do you know how many CAD programs out there?
To many.
Years ago the manufacture guys provided files for Orcad and a few others.
Today you have to draw it by yourself.
Take the datasheet and create your own.
When you are finished with your part triple check it before you use it in
the schematics or in the layout.
Cheers

You are rigth BUT, I think chip manifacturer has it's own chip database so
the company can do some automatic conversion to some well described open
format.
I suppose KiCAD or Geda has free formats but I can not see any progress

Dimitri, it's like to write a Software.
You will always have people how likes it and others how don't likes it.
It is impossible to satisfy all people.
Thats why the manufacture don't provide the CAD files anymore and nowadays
it is very easy to make one by yourself.
Mostly the package already exists. Now you only have to draw you schematic
symbol and add a netlist or under Eagle connect it with you package.
Thats it.
I have drawn hundreds of elements by my self to satisfy my needs even when
there was already an existing element.
kicad and geda are nice opensource tools but they are no match to the
Altium or PCAD or other big tools.
But they are not widley used in the professional sector.
So at the end there is only one way.
Do it yourself and have fun.
Cheers.

I do electronics for a living and have been constructing our
own component libraries for about 25 years now. We have used
expensive commercial software for the better part of those
25 years and I did not like the standard component libraries
that came with it. So we drafted our own. And it is a simple
process if you get the hang of it (some software will make
it a very difficult process, true).
Nowadays we use Kicad and I have started drafting our own
libraries once again :-)
(I do NOT like the use of the name "modules" in pcbnew for a
component. A module is a collection of components on a pcb
for instance, a single component is NOT a module.)
When an IC manufacturer draws a component for you to use it
usually is in such a state that you still have to draw your
own or change it because connections/pins are in the wrong
position (for a good schematic flow).
Just draw your own components :-)

Hey Guys
Thanks for the replies. I guess I'll edit and make one for myself.
I was just hoping if somebody already had it and could share it.
I understand making those CAD files is not a complex task however I feel
sometimes lack of such basic tools distracts a design engineer from the
'basic core task' to the 'side tasks' and creates "avoidable delays" to the
projects. (reinventing the wheel !!?)
Nevertheless I still believe that the silicon manufacturers can provide
this kind of support at least for the famous and widely used softwares.
(On many occasions they already provide special application notes for
IAR/Keil/Eclipse considering the fact that there are many more IDEs. If
they can do that for IDEs then why not CAD ! )

Rather than starting from scratch, if I were you I would start with the most similar existing Eagle library file (e.g. the LPC11C12/14-LQFP48?) and edit that. As far as I can see, the pin numbering and at least some of the pin names are the same.
You can download the NXP-verified 'EAGLE Parts for LPC11xx' library files from NXP's LPCware site:

hmmm wait a minute... You are telling me that "it's like to write a

I am not a good programmer (well I think I am gooood but let imagine) ) -->
that I have with my favorite LPC2468? -- a lot of free sources and
libraries and examples and also trailware uVision and etc. LPCware.com,
LPCexpresso, EMBED
Just open Keil -- select MCU -- you have all pins and pheripherals and etc.
I am opening KiCad or P-CAD or Altium -- there is my favorite MCU ? there
is library for my favorite MCU.
You will always have people how likes it and others how don't likes it.

Shure it is impossible to satisfy ... what is why You can connect many many
chips to LPC2468 and write many many sources and libraryes but the names of
registers is almost in 99% of cases is the same that is why we have
standards like CMSIS

I am sure that this is a question of format. Making conversion tool from

4 times 208 equals 816 ???
I guess typo....
I have no idea what kind of schematics you draw and no intention
to find out. But 208 pins is still 208 pins after I or anybody
else have entered that into CAD schematics. NOT 832. You must
have been drawing some pretty unreadable schematics (for others
to read and/or follow).
One IO pin is still one IO pin that is on the component package
and the number of sub functions does not matter for that.

I'm not quite if you did get my message.
The software was a metapher that even when the chip manufacture will
provide you a schematic symbol, mostly it wont fit your needs.
The same can happen with software, depending on your requirements.
If you find the source of a program it can easily happen that not all of
your requirements are covered.
So what do you do?
Complaining to the author that all functions which you will need are
missing?
I guess no.
You will check the code and then you try to add those functions which you
think are missing by yourself.
The same with the schematic symbols.
As mention from some one else before.
Take a similar symbol and modify it for your needs.
Thats was my message.
Especially about the LPC11E14 which has an LQFP48 package not over 200.
Better for the next time would be to ask in the forum if someone has draw
the schematic symbole for Eagle already instead of complaining about NXP.
