I thought that would get your attention.

W (http://www.parallax.com/Store/Microcontrollers/PropellerChips/tabid/142/CategoryID/18/List/0/SortField/0/Level/a/ProductID/801/Default.aspx)hat? No discount without the the Beanie ? :)

EDIT: At least the QFP's have a decent stock level now.

I think it's unmarked due to the use in a professional settings the use off "hobby chip" will be locked down on.
And not unmarked due to trying to hide the circuit layout with IC obscurity.

Yes, It is probably meant to be an chip sold to OEM's. That was my thought.

But the Bernie adds five more HP like Racing Stripes on a car. :)

Publison you got my attention all right. Good job.

It would give the chip some class.:smile:

The unmarked Propellers are for customers who have requested an additional piece of protection for their intellectual property.

Uhm, kinda hard to hide that particular die style from fluoroscopy. Besides, think in terms of opsec. The mystery chip is unmarked, but has certain clock pins, certain power/ground points, familiar por/boe passives....hmmmm looks like we eliminate all candidates not 3.3v 48 pin footprint....narrows down the id pretty fast. Pull said chip w/ rework system and drop into test prop ckt or arm ckt end result positive id and then suck down the code .....IP now not so secret........

People at huge med OEM used to snicker when I would mention wynn schwartau and others......... we'll, well.....

I think it's to take care of the causal hacker. We all know practically anything can be hacked. :)

...The mystery chip is unmarked, but has certain clock pins, certain power/ground points, familiar por/boe passives...

But that sort of information isn't readily accessible as an index to a chip. When searching Mouser, I don't see an option for "Clock on pin(s) 28-29". Unless the attacker knows about the Propeller anyway, it would be difficult to guess based on that information.

If you can figure out it have 32 i/o and that it's LQFP, then the choices do narrow down.

And find the one with 44pin and you left with 2-3 choices.

Or just image google 44pin QFP mcu

Ken hooked me up with this version last year. I have been using them in my prototype designs. I had them laser marked with my company name.

As a suggestion here- maybe Parallax could offer laser marking these as a value added option?

Laser marked by Parallax?

No laser marked by a company near me using a YAG laser. They also laser marked the aluminum case of my product.

Yes. Minimum order quantity is 2,500 units and the unit cost is 15 cents each. Setup charge is $250.

Ken, nice although I would have thought it better to keep this under wraps.Thats 25c per unit in 2,500. Well worth it to keep the honest thieves away, and theres a reasonable discount for 2,500 units anyway ;)

In reality, if the product is in a commercial design (not the typical home user), not a lot of companies will bother. And those that look up the part will not find it and may assume its a custom ASIC. Most professional companies have far better things to do than to steal and produce their own. And opposition companies have to get some to attempt it.

Don M: May I suggest next time you place a nice part no on it. Something misleading like a similar part to an ASIC.

The hacker is the one to worry about with IP.

I agree with you.

Most professional companies have $625 to spend on 2,500 units.
