maybe someone can compile a list with MCU's/CPU's you can really get free as a sample request???

Like:

ATMEL: AT91xxxx ARM7TDMI core, free samples from www.atmel.com

hopefully a lot more???

You can request pic micros from www.microchip.com if you don't live in Poland, Turkey, Russia, Hungary, Romania, Ukraine, Bulgaria, Czech Rep., Bosnia, Africa, Yugoslavia, Egypt, and Slovakia! I can't request!

I'm surprised no one has spotted this one let:

Lattice Semiconductor Mico32 32-bit RISC microcontroller
http://www.latticesemi.com/products/intellectualproperty/ipcores/mico32/index.cfm

Distributed under GPL license.

Verilog 2001 RTL Source-code
GNU toolchain (GCC, BINUTILS, GDB), etc.

===

The RTL needs some hand-modification to compile in Xilinx Webpack 9.1, or qu(at)rtus II 7.1. (Simple changes...)

Guys... don't get side tracked.. free means the design is open with VHDL/RTL code... not free samples !

I am considering setting up a global free sample distribution point, my company would buy the chips and ship them out to places the other companies don't allow so long as it does not break any trade regulations. Included would be items such as gps modules, atmel and microchip MCU,s A/D converters, Lipo's video capture units, DSP's etc. There would be a requirement to state what the project is and what you expect to get ou of it, we would then make an agreement to send the items for free in return for a 1% share of profits if the item is commercially sold.

I'd be interested in you guys feedback regarding this , to see if its worth doing.

Several problems with this business-model:
1) lack of enforcement: how do you verify if customer is honest? They might just take a bunch of free samples, and run.

2) lack of tech-support: if you are not an authorized distributor for the parts, then the vendors give you no tech-support. If your customer is serious about developing a product using those parts, he will need some kind of tech-support. The major US semicon distributors (Avnet, Nu Horizons, etc.) have many field application engineers to support lower-volume customers. Higher volume-customers deal direct with the part manufacturer. (I.e. Dell goes directly to Intel, they don't go through any distributor.)

3) non-sustainable business-model : in shareware industry, less than 2% of users actually register. Out of all the free samples you send out, how many will result in actual sales revenue? Probably less than 2%. Can you make money this way?

...

And to add to the free-CPU list:

It not ment as a profit making venture, any losses will be offset against tax and it is intended to allow the multitude of developers out there to have a go.

And in respect of my potential payback, all it takes is one design that makes it, loosing parts to people who take and run is all part of the deal, if people ar5e found selling them on ebay then they will no longer have devices sent to them, Also these parts are not ultra high in value anyway and samples would be limited in number for any given period preventing people from using it as an income.

My goal with this project is to prevent the frustration I had for many years being turned down by companies for free samples, today with a major backer I turn unsolicited sample deliverys away, the system is not set up correctly.

The ideas are out there, they just need some backing, as for technical support, thats where this forum and others like it come in, I doubt very much if many people here call microchip to get help, when it comes to OEM equipment such as gps modules we will be shipping our own design and select others all of who have full data sheets and specs available and as ever theres the boards.
