Why not create it yourself? It would only take a few minutes with the PCB software I use.

Steve, your spam load is about to go off the charts.

Use any tqfp-32. They are all essentially the same.

I was always worried they might be different pitch: .5mm .8mm...

As far as I know "TQFP" is one pitch. Other pitches are called by other names. Things like "Fine Pitch TQFP". But, the OP can check the pitch on a footprint and verify that it is correct, if that is a concern.

Hmm, I did that once. Then the parts arrived with 0.8mm pitches and wouldn't fit my 0.5mm pitch PCB. Ended up having to make 0.5mm pitch adapters to QFN parts which took me a long day each to solder and get correctly connected. Will never EVER take part footprints for granted again...

Electronic components work on the principle of smoke; I know this because when I let the smoke out, they stop working. Also, sanity is over-rated.

Check what, two years later.

 

Looks like pseudo-spam to me.

I think that was just a question in (misunderstood) response to Torby's warning that publishing his email address would open the OP up to flood of spam.
I don't understand why a two-year-old thread has been revived...

Ah, I missed that.

 

I generally try to have the key components in hand, before I lay out a PCB, just so I can lay them on a print out of the PCB to make sure 0.5 vs 0.8 pitch pin-out isn't an issue.
