I love Atmel, they make the best micro controllers at the best price... Look at this http://www.bajdi.com/?attachment_id=469

(Atmel has just implemented a new Sampling Scheme, BTW.  Traditionally, it was supposed to be difficult to get Samples of Atmel chips.)

Note that if you're a "real company" of the sort likely to use tens of thousands to millions of chips, a sample request is likely to be answered with an offer to send around a sales team, engineers to assist you with your design, development tools, and more.  Which goes back to what I said about samples being cheap marketing.   Even the 5 minute phone call is likely to cost the company more than the sample chips themselves (and I suspect that the infrastructure to support sampling for the customers that really "deserve" it cost more than product they send out.  (applies to the sort of avr-class chips I assume we're mostly talking about.  If you start phoning places up "I'm working on a new guided missile system for the army, and I'd like to get a sample of your $300 mil-spec 9dof inertial navigation chip...", you've probably crossed a line.)

I've found Texas Instruments to be very generous and fast with their samples.  I don't try and order once a week or anything though.

Those are interesting chips but I think I like Atmel better, at least on paper.  These seem to compete with the ATTiny line, but as a 16 bit processor.  So they have an advantage there, but all the options seem to be 2KB flash/128 bytes RAM/0 bytes EEPROM and even the modest Attiny 44 has 4KB/256/256.

 Some samples I have got:

I got a STN1110 chip rather quickly after asking for it. Here is a bit of info that I quoted from a thread where I got the info.

Quote
STN1110 ICs from here: http://www.obdsol.com/stn1110/

The STN1110 chip supports all the OBD-II protocols. If you want something a little more user-friendly (and a little more expensive) you can also get the ODB-II UART board from Sparkfun (http://www.sparkfun.com/products/9555) which also uses the STN1110.

Or you could build your own version of the Sparkfun board using their schematics.

I got an STM32F4 discovery board from ST, www.st.com for free which was nice. I struggle with using it but, it is a nice board!

Most recently, I got 4 chips from Atmel by filling out their form for receiving samples. I have a thread about that here in bar sport.

In each case, I answered honestly, and had no problems getting the chips.

Anyone else have any luck getting samples?

Oops that made me laugh :-). I went back and corrected it to ST www.st.com.  I had second thoughts when I was writing that line, good catch!

 Repost to the thread where I plan to keep my sample info in:



 I got my EEprom From Renesas today! That was quick! "About a day or two."

3 piece HN58X25256FPI#SO

IC EEPROM 256K 5MHZ 8SOP

Now I need a way to solder it down!

Datasheet says 8SOP version is 1.27mm.  Does that look right?  That's a big pitch for a modern chip.  But if it is, you want an adapter like this and 2x 4 pin headers:

http://www.ebay.com/itm/10PCS-SOP8-DIP8-adapter-PCB-converter-0-65mm-1-27mm-/140866822761

http://media.digikey.com/pdf/Data%20Sheets/Renesas/HN58X25128I_256I.pdf

That is big enough you could probably just solder wires onto those pins directly.

Boy, I want to get better with ARM and I like the fact it is in a DIP but I would rather use a programming environment that is not a BASIC compiler tied to a small company.  I bought a STM32F4DISCOVERY board which has a F4 chip from ST on it at 168Mhz and I intend to get busy with that after I finish my current little project which uses a 328.

OK, I am self-bumping.  I hope the church doesn't hold this against me.

To amplify a small incoming signal for a counter project, I have just sampled this fine product.  Wish me well because I have never used one of these before though it looks simple enough:

http://www.ti.com/product/pga870

From Atmel I got a couple of XMEGAs and a couple of AT32UC3s.  I want to prove that I can make these work as easily as I make ATMEGAs work.

Microchip has sent me a few 8Mx16 Flash ROMs.  They program in my ChipMax II well.  Got an idea for these.

http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en549454

And Fairchild supplied some very high speed counters for the counter project too.  Just came today.

Anyone else?
