Hi Paul;

I'm afraid that on this one I have to side with Dan. My company is in the middle of a huge design effort in which the SX series is used as well as bigger processors.
We have deployed the SX52 on about 8 circuit boards; not particularly that we needed the extra 4 pins, but rather that we standardized on the larger pin count, should we need them in future products.

While I'm certain that Parallax is fully committed to supporting the supply of SX48's, the rapidity of the disappearance of the SX52 was rather a shock. I believe it would have been appropriate to give some more warning. I agree with you that osolescense is a fact of life in our industry, but a one year, or even 6 month end of life warning would have been adequate. Even some suggestion that for "new designs use the SX48" is something that industrial folks require; for the hobbyists I see it as less of an issue; costs there are "softer".

Sure, we all can deal with the lost port bits (darn it), but now to transition to the SX48, I have some new cost that would have been avoided or minimized if I had known about this earlier.

I'm still loving the SX, and will continue to use it, and other than this episode, I DO appreciate the professional manner in which Parallax conducts themselves.

Let's just call this one a tactical error............. so keep up the good work Ken!

Cheers,

Peter (pjv)
