My guess is that there is something different about the
designs/applications which are experiencing the lockups/malfunctions -
too many products use the FTDI USB to UART parts successfully. Among
many others are the Arduino Decimila and (Digi) XBEE daughter boards.

Hi group,
Does anyone have a sym file for the FT232RL?
FWIW - I'm using the FT232RL in a converter that switches 7A at 350VDC
without problems. My circuit doesn't have the 47pF caps on the signal
lines and the shield is connected to ground on the target board,
As for the footprint, I found that the pads DJ's footprint were a bit
too short for me to solder comfortably - I added 20 mils to the outside
dimension on both sides and it was a lot easier.
I did the same thing on my production boards.

I don't plan on etching a board, I'm using wire wrap on a pref board. Still
researching what and how to do it. I have a plan on how to mount the
IC using headers, making it look like a DIP IC. We'll see if it works!
Thanks to all that have replied to this post. You have been very helpful.

I do. I have the .symdef for djboxsym too, if you want it. I also
have the corresponding footprint.

But I might have horrible symbol styles I learned from Autotrax that
others dont like.

Ah, the perils of open source. With proprietary software, your
problem is not enough symbols. With open source, your problem is too
many.

Heh, I like that idea the best! Then there's no question about the

That's the BM. The OP is using an R, which is a different chip.
Unfortunately we did experience this problem on all of our boards.
