View Full Version : P8X32A-D40 Shortage Expected by August 1st, 2009

Hello Propeller customers,

We are projecting a shortage of P8X32A-D40 (the DIP) processors relatively soon, perhaps within days after I post this message. The shortage will occur as a result of two variables: (a) increased demand for DIP parts beyond our projections; and (b) underestimation of several lead times in our enterprise resource business planning software.

We don't have accurate replenishment dates at this stage, but our preliminary projections are to have more P8X32A-D40s in stock by October; from history I assure you the date will change +/- 30-60 days. We will update this thread as our suppliers confirm our orders with actual delivery times. As you may know, fabricating chips involves several steps. First, wafers are made at the foundry. Next, they're sent to a packaging company. Finally, they're tested.

We do not foresee shortages with the P8X32A-Q44 or P8X32A-M44. The replenishment of P8X32A-D40s will include more inventory of the other two packages, too.

I post this to the forums because there are several Propeller tool and board providers present, and we feel it is important to give them some priority and advance warning.

Because of this shortage there will be no free or discounted P8X32A-D40s. Occasionally we have traded chips for customer applications or other purposes. Some level of ration-based distribution will be left up to Jim Carey, our Sales Manager.

Sincerely,

Ken Gracey

Ouch, maybe it's time to learn to solder surface mount Props? I have to admit, I like the DIP chips for the ease of changing out IC's in sockets if required.

Is it possible to use the QFN package chips and mount them into some kind of socket (like a Pentium CPU) so they can be switched out without soldering?

@OBC

I'm talking about using the QFN propeller chips, the ones that have no legs, and instead of soldering them to the board dropping them into an IC socket of some kind for easy replacement. The latest Pentium chips are similar to this concept in that they have no legs and are simply placed into a holding socket on the PC motherboard, which is locked down with a retaining arm.

It looks like something along these lines is offered, found this link whilst googling:

You could also make/buy a PCB DIP "Adapter" board, and solder on the QFP version, at least in the intermediate term. Not easy, but better than having to redesign PCB's like the MultiBlade/SpinStudio/Morpheus.

Ken,

Would it be possible for Parallax to create a variant of the PropStick USB where only the essentials (prop/eeprom/crystal) are loaded?

I don't believe the PCB would need modification; just the loading pattern

I believe this would be the simplest solution for we end users, while using an existing Parallax design framework

FuturLec (http://www.futurlec.com/SMD_Adapters.shtml) has some simple solutions for using QFP chips in a replaceable format, check out the 44 pin TQFP Adapter (http://www.futurlec.com/SMD_Adapters.shtml), $1.20 each.

This is still not exactly what I was hoping for, something similar to >this< (http://www.futurlec.com/Sockets/PLCCS44.shtml) would make things much simpler. I'm hoping to be producing my own automotive product based on the propeller in the very near future (still a work very much in progress) and like the idea of a whole unit not becoming scrap (in the customers eyes) just because one chip needs to be replaced.

SMT really isn't such a miracle and can be done by hand as fast as through hole parts. And even replacing them is in fact faster (as long as you don't use sockets, but I wouldn't use them in such an application anyhow).

Why wouldn't you use sockets in an automotive application? Because of vibration or simply personal preference?

Painless,

Vibration is the reason why you go with soldered components vs. sockets. Also from a repair POV with the right equipment its just as easy removing and replacing SMT IC's as socketed ones.

You're right, SMT's are also so much nicer in terms of space. If I wanted to try some SMT work what would I need other than a much finer soldering iron tip?

Vibrations, condensation etc. If you use sockets, they will have to be high quality and they cost a lot. And maybe you think about coating the assembled PCB with some PU or so. Then the socket's advantage is lost, because you can't pull out the IC any longer. http://forums.parallax.com/images/smilies/smile.gif
I don't want to drive you into SMT, but sockets in a production product are quite a waste of time and money. In my eyes.

Back in the 80's we did a study on faults on pcbs returned and found the vast majority were socket connections, often fixed just by reinserting the IC. We ditched the sockets and the faults dropped dramatically. This is besides the cost savings, but of course, without equipment you cannot swap/remove the IC.

Ahh, you are too kind to us. There's no reason for thanking us for providing bad news ahead of time.

Here's a bit more detail about your demand. This graph shows our P8X32A-D40 sales for the last year. Parallax must supply DIPs for prototyping and some low-volume production, yet they are not the kind of package alone on which we can base a chip business. Our sales volume of this package increased the last couple of months, as you can see. Our projections for DIPs were relatively flat, representing an average of our monthly usage. However, a few "big" months changes the picture quickly. If the dollars from P8X32A-D40 sales are relatively low, why didn't we just buy some more several months ago? Because there's a minimum order quantity (MOQ) for Propeller wafers. Basically, we'll need to spend 1000x (or something like that) the monthly sales value of P8X32A-D40s to replenish the inventory for this package type. The wafers can be made into any Propeller package, of course, so some of them will be QFNs and QFPs. From history, though, we'll be making more QFPs than QFNs.

@cluso99 & Nick

Thanks for the insight on this, it makes a lot of sense. I have to admit that the idea of not drilling umpteen holes in a PCB is a very inviting one, with some practice I'm sure I could get used to surface mount parts, my eyes aren't what they used to be but that's nothing a magnifying glass can't cure http://forums.parallax.com/images/smilies/smile.gif I blame all those early years of staring at fuzzy old green screen 3270 terminals.

what can we - your customers - do to be of assistance?

How about Planned PropHood ? :))

We pre-order and pay into an escrow-like account, knowing we have to wait. When we hit the magic number, you order the batch. And we become happy prop parents ( - with no messy diapers to boot! )

Since you've graciously shown an internal sales metric, my I ask what led to the spikes in Sept-Oct08, Feb-Mar09, May-June09?

Ken: Gee, you guys are great, even publishing the graph.

If I may pass some comments on the demand graph...

As you know there has been a great deal of activity this year with new designs and software, the prop has become of age, at least in the hobby community. The introduction of multi-prop pcbs has meant more usage.

The dip in May may be due to the price drop notification where stockists were clearing "old" inventory (cannot recall the exact date).

The pricing on the prop has now meant that using it as an "intelligent" peripheral to other chips is cost effective. e.g. PropTerm is being used by the N8VEM (Z80) guys as a terminal.

With more pcbs being released and operating type software coming, I can only see demand going higher http://forums.parallax.com/images/smilies/yeah.gif

I have one saving grace. My SpinStudio Mainboard contains a DIP Propeller, but....

OBC's Propeller Cookbook contains a section entitled - "I Think I'm a Clone now - Turning a ProtoBoard into a SpinStudio (http://ucontroller.com/cookbookexcerpt.pdf)"

So If Propeller DIPs dry up, it's possible that customers could still buy peripheral modules and use them with a modified ProtoBoard.

I also created a Mini-SpinStudio - but never released it due to the assembly time on my end that would be required. Maybe it's time to roll that one out. I included a photo of this board design...It has everything the SpinStudio has, plus onboard USB programming circuit. The peripheral modules plug in, 1 per side, as opposed to the current 2 modules on 2 opposing sides.

I know... I am in a similar situation. I have a small stockpile of Propellers for Morpheus - but they will only be sold as part of a Morpheus kit or assembled and tested Morpheus board.

http://forums.parallax.com/images/smilies/sad.gif It appears that the Propeller shortage is upon us

Any news from Parallax on when more stock may arrive?

On uController.com, I've stopped selling Propeller's ala carte for the time being, However the SpinStudio Mainboards still include a Propeller.

To put a spin on Matrix: What will really blow your mind is that did they run out because they told us they would or if they kept it a secret would it have happened much later or not all.

Probably would have happened based on the data Ken shared.

Hey there, I expect more P8X32A-D40s in stock around October 1st at this stage (60 days). We have a small emergency stockpile but they are generally dedicated for products like the PE Kit and they will not be available for sale via our web site. This shortage will last a while -- sorry about that -- we're working to push along the various steps of the process from wafer => packaged chips => tested chips => stocked chips. This whole process happens on four different continents. Propeller chips travel more during birth than most of us do in a whole lifetime.

Since I've had my own issues with this..... Who wants to help Parallax and write an improved "enterprise resource business planning software" in Spin?
It should use ucontroller.com's ethernet adapter to periodically query the parallax.com site and look for products that will run out of stock soon (based on data from the last 2 months). 32kb of RAM should be enough to do handle several thousand products. It's not rocket science...

@Hanno, we stock 900 items. As I have told you personally before we have a very capable business enterprise system and our inventory accuracy (physical inventory vs. software quantities) is 99.97%, higher than nearly anybody in this industry. Looking at the Parallax stock values on our web site only tells you a rate of change each day or month, and it has nothing to do with supplier lead times, unique customer orders, safety stock, economical buy quantities, minimum order quantities, etc. Forecast and demand gaps alone can throw any inventory planning aside. It's not rocket science, but it's also not as primitive and simplistic as you believe - such a procurement channel is stuffed with humans to add a complexity that software would also have trouble predicting. The tools we have work well provided the variables are properly managed.

@Ken. Having worked on and even written some inventory planning software over the years, I understand what you are going through. Unforunately, no matter how good your software is, it cannot predict abnormal demands as you showed us on your graphs. No human could have done better even with as much time as required.

As someone who has done his best to promote the Propeller, I'm pleased to have
had a small part in running down the inventory. :) From my perspective
it appears that the demand is increasing faster than anticipated by Parallax. Nice.

Bottom line is that Parallax must actually be successfully selling product to stay
in business. Sounds like the Propeller chip is selling...

As long as they don't run out of Protoboards I won't go into panic mode here. :)

@Ken,
I totally agree with you that a complete business system is necessarily very complex and I love referring people to you- they always end up happy dealing with Parallax.

I still see this as an opportunity for someone to win the current Propeller challenge with a highly simplified inventory alert system. I realize that predicting anything- let alone human behavior- is hard, but think how impressive it would be to casually show this on your next Parallax tour- it might even be an app that other people would pay money for:

- Propeller DemoBoard hooked up to a widescreen tv and connected to the network.
- Once a week it:
-scrapes a website that contains stock data- it creates the url's dynamically using stock codes- so we'll allocate 1 word to store the stock code plus the code/memory required to download/parse a website for a single number- this is the hard part of the problem...
-manages a queue of the last 8 weeks of data for each item, we'll need 8 words of data/item for this
-uses a very simple model to calculate how many are sold/week, weighing the current data higher than older data:
weeklysold:=(week1+week2+week3...+2*week6+3*week7+ 4*week8)/14
-adjusts the weeklysold variable by the weeks of leadtime required by your supplier. Then it compares this to the stock on hand, and if too low, prints it to the vga
if(weeklysold*leadtime>stock) vga.text("You're low on this item"+item)

This system would display which of your 900 items are in danger of running out within each item's leadtime.

Like any system it's not perfect, but hey, it's a simple inventory alert system that runs on the Propeller- and can manage roughly 1200 items! (16kwords/10words/item +program)

Keep up the great work, this is a GOOD problem to have!
Hanno

@Vaati,

No reason you shouldn't! I just confirmed that with Sales, and that kit is indeed in stock, Propeller DIP chip included.

If you ordered through our website, you can always email sales@parallax.com and give them your order or customer number and they will check up on your order for you. Or, you can call toll free in the lower 48 at 888-512-1024 (elsewhere call 916-624-8333).

Just thought of this while responding to another thread.

You can make a Propstick to DIP40 adapter out of 2 stacked 40 pin sockets. Just remove pins 10, 12, and 32 from the bottom socket (IE to remove the connection for the 5 volt input on the propstick) and solder wires to pins 10 and 32 on the upper socket to reroute VIN and 3.3 VDD out that didn't exist on the DIP40. You may have to remove pins 37-40 on the lower socket as well?

Yes, I know, there is a small price difference http://forums.parallax.com/images/smilies/blush.gif, but if you have a propstick in your propeller arsenal, you can use it in the meantime while waiting for DIP40 stock. Or if you are really DIP40 desperate, a propstick isn't a waste of money if you go that route.

The wafers have been received at the packaging company, and we expect to have packaged chips under test within two weeks. This would provide a delivery date to Parallax by the last week of October. And this shortage will probably not happen again because we’ve made provisions in our planning tools to protect our customers from internal human errors.
