How possible would it be to provide the surface mount SX's in a slightly larger package?
Like an SX28 in SO-28 instead of SSOP-28.
I have been messing around with surface-mount designs and the hardest part of a "do it yourself" SX-based project is the fine lines required to mount the microprossesor itself, especially for an SX48.
I know about the protoboards, but it's like trying to build a sub-compact car on a Mac-truck chassis.
Since it's obvious that the line-foreman from Parallax is about to fly out here and hit me with a bat, I will scurry back down in my basement and fry a few more components.

The SX28 used to be made in an SO28 package. I have some if you need some of them.

Have you heard of our SX Proto Boards before?
I quit playing team sports before I started, so I have no bat. I have wine bottles though.
Instead of playing Whack-a-Mole on·a customer, I'll give you the corporate line. Electronegativity, Parallax is your company. Without you, there's no us. And there is a you without us, so this synergy depends on us serving you.
Just in case you were serious. . .·what about those SX28AC/SOs? We'll look into more package·styles once we get our·new Parallax SX·devices underway. I'm expecting the first Parallax-labelled and packaged parts next week from our new packaging supplier. So many parts are coming that my Purchasing Manager is a nervous wreck.
And when we've got through the first qualification and·the engineers tell me everything is okay with our new parts, then we'll look into some new package designs. But I have to tell you that you are the first person to ask for an SX28AC/SO package. These were discontinued a long time ago due to low volume. In fact, I'd rather send·Gary (our SMT internal hero) and his equipment to your·nearest McDonalds or other meeting place [noparse][[/noparse]for free] to do your SMT work on site. This would be a·cost effective decision compared to Parallax making more SX28AC/SOs, because·mainly you will buy them. And no matter how fast you work, you won't be able to consume more than five a day.
Bean is my hero right now. And I'll check our inventory for you, too.
So far, here is what seems to be most popular as far as a new SX is concerned:
Yours,

I have about 40 I can sell you for the same price as the SX28SS if you want them.

Looks like, if Parallax don''t want to start up the package again, and the volumes really are low, there's enough out here to get by...

I'm suprised and happy to find out they actually exist, and sent Bean an offer.
When my skills increase it may not be such an issue, but for now it's not just the soldering, I'm also making my own circuit boards and my life is easier if I don't have to etch 15 mil lines.
The thing that got me started on SO-28 is the SO-18 Darlington arrays I got from Mouser.
If I use an SO-28 SX then the pins will line up exactly and I can etch straight 30 mil lines between the two.

Have you actually taken a survey of the most popular packages?· I've read suggestions in the thread where Parallax announced taking over the SX, but I haven't seen a survey.
My vote would be the SX18 at under $2.00.· I think this is a really important gap in capability and price point that has been taken away.
And I think Bean suggested an 8-pin and a 14-pin which would be very cool also.

Thanks,

It's Only A Stupid Question If You Have Not Googled It First!!
I'm trying to keep up here, and am seeing mixed signals from a couple sources (including the possibly not updated "sales" web site. Isn't the SX52 a "dead" issue? Or is it just one specific package configuration that has EOLed?
The SX52 is not only mentioned here, but still mentioned several places on the sales site.
I'm not trying to be a jerk, and realize that sometimes events happen faster than resources are available to handle them, and priorities have to be set (poor Jim, the IT Guy). I'm new to this stuff, starting to get really interested in trying some of the products in addition to the STAMP, and trying to grasp what's going on.

Basically, don't start new designs using the SX52. He is ticking off desires of customers, which may or may not come to fruition, and I believe the package he mentions is a different size than the old 52 because the die is too big to·fit in the old package without machining the package.·

Time to order a lot of Proto Boards!
Why is the die too big to fit in the case, when the SX48 is almost the same and is in a much smaller package?
▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔
SX-Key + SX52 + Proto Board + SX-Key Software + Computer + USB to Serial Adapter + LED = Blinky LED!
But before that happens, there are several other SX changes abreast at Parallax:
- new SX datasheets for Parallax parts to be published (December)
- Parallax SX parts to be qualified and tested prior to sale (December)
- RoHS-compliant parts to be added to inventory (December)
- New SX Blitz and new SX Key redesigns to be sent to fabrication (December/January)
- SX28AC/SS Proto Board to be sent to fabrication (December)
- SX chip and tool prices to be adjusted based on new Parallax costs (December/January)
That's a look inside Parallax. Many of these activities are already three weeks late. As for choosing more part packages, we'll seek our customers input before making any decisions. I'd like to know what Chris thinks if the SX28 were under $2 - would that meet your needs or do you really want an 18-pin part? As you can imagine, there's a fair amount of research we would need to do even after our customers decide for us. Honestly, we've got our work cut out for us right now without considering new packages. I can't envision considering a new package prior to February.

These 'form factor' changes are really a challenge. First one thing, then another.
The package change implies that the SX-52 Proto Board will have to become a separate design [noparse][[/noparse]different chip size requires a differnet board] and may never come to be.
How many current design SX-52 Proto Boards on hand until they no longer exist?
Should we stock up?
If the SX-28 is under $2, I personally could afford to ignore the extra pins and be very very happy.
But I am having trouble buying the narrow 28-pin DIP sockets.
Fortunately, I seem to be able to use two 14-pin DIP sockets end to end.
Seems like I will have to solder them directly at some point in time.

I could learn to live with the extra pins.· Would the pricing be the same for SMT chips?· Size matters, ya know.

The SO version is the same pin-out as the DIP version. And I'm another one that would love to see the SO version again.

You have requested that the SX20AC/SS drop below the price of the SX28AC/SS. It will, as soon as we resolve our new costs. However, in the meantime I've been able to·locate 721 SX2AC75/SS microcontrollers in our inventory, which will soon be posted to this location on our web site (within 24-48 hours):
http://www.parallax.com/detail.asp?product_id=SX20AC75/SS
These are the same as the SX20AC/SS, except they were tested at 75 MHz. These will be $1.95, any quantity while supplies last only.
Ubicom discontinued the 75s quite some time ago, but we're in the middle of some housecleaning and we would like to move these out of our inventory as we further prepare for our transition.
If somebody wants to buy all of them (got a project that uses the·SX20AC/SS?) and would like to have a better price, please see me.
