| If anyone is interested in an ultra cheap ARM development board ($4.99 delivered to your door in the US) send me a Personal Message (PM) and I will send you a link to the page. I will not post details here because it is not a Atmel product. To the moderators, if you feel this is inappropriate please delete this post. |

Could it be TI's Stellaris® LM4F120 LaunchPad?  |

really low end ARM CPUs don't appeal to me. By this, I mean 64KB flash and less, or 32KB RAM and less. Arguably, this is on the borderline where an 8 bitter is better.
But, a cheap teeny ARM is perhaps good for microprocessors 101, or such crude tools that go with it can be a bad first impression, vs. use of JTAG debugging and so on. |

Delivered to my door in Australia. I felt guilty ordering these as the shipping would exceed the price I paid.

I ordered two. The automated response tells me they should be shipped in December. A Christmas present maybe??
Atmel - if you want to gain the hearts and minds of most of us here, jump on the bandwagon of cheap development boards with debugging. Maybe the hope is that the Arduino Due will perform this role? It's a crowded market, so you have to dangle a nice carrot.
Basically TI is doing a loss leader to get your email address so they can send you out blurb on their new products. Since they have such a broad range, they're bound to get hits even if it is for a volt reg or fancy op-amp. I'll whore myself for goodies.
Never underestimate the cost of advertising. My employer is paying Google around $0.70USD per click through for targetted advertising. Considering us bunnies have actually paid money to order these boards basically qualifies us as real customers that will potentially buy their chips.
Don't worry Atmel, I've got at least three products still in production for the next two years using your product. |

Yes, fine..
If you're optimistic instead of pessimistic then instead you look at this:
http://finance.yahoo.com/q/bc?s=ATML&am ... q=l&c=
(1 day graph - wich, at the time of lining showed a positive trend)
or this:
http://finance.yahoo.com/q/bc?s=ATML&am ... q=l&c=
(graph from early '90s until today - high fluctuations but still a slightly positive trend).
I hope that they use the stock value as a secondary indicator, and actually focus on their P&L/revenue statement. (Yes, the stock value is linked to this, but only in part.) |

| It's not mæk hæk by any chance? Doubt it because it's basically a hobbyist project. |

I just ordered 2 stellaris launchpads myself, and previously bought 3 launchpads with the MSP430. We've been working with the TI stellaris ARMs at our school previously so I know a bit about them, nice product but unfortunately code composer studio is limited to 16KB program size (at least for MSP430) in free version! Don't know if that limit applies to ARMs too?
I've been registered with TI for many years (samples  ) but never received news on new products and such, so it's definitely not for "e-mail harvesting" they are doing it!
If Atmel did something similar (I'm talking price here ) with the AVR32 or their ARMs I wouldn't hesitate to click the buy button! |

Using TI’s Code Composer Studio IDE for free states "... no code or time limit."
IDEs for ARM - many alternatives.
Another plus for Atmel Studio. |

I think they charge a dime for every item in the errata, so maybe they discovered some more (and could be coming out in a hard cover edition), or the price per errata went up.
(I hope TI has no black ops unit) |

It's still at $5.18 at digikey (plus shipping), although I wouldn't bet on it staying there for much longer. Not in stock, of course.

MSP430 is a truly wretched microprocessor.
take it from a victim. |

| Steve, not having used a MSP430, can you enlighten us with the problems you had? The MSP430 seemed to be the low power leader in its class for some time, but I had no reason to stray from the AVR. |

Opinion alert:
MSP430's architecture is bad. Esp. when the program gets large enough to not fit in 64KB. god-awful paging scheme. And the public domain GCC doesn't support paging. And TI's IDE and software ($$$$$$$$) is not good.
But TI always has a following, from inertia.
This is so not-Atmel-topical..
Opinion alert: there are far better choices for 16/32 bit very low power processors than the and ancient MSP430. TOday, most such processors are in the ARM Cortex M0/M3 world, and some are very low power consumption.
SInce this is Atmel's web site, I'll not name names. |

Just being pedantic but it's not public domain - it is GPL. |

MSP430 rant, couldn't resist:
I kind of wanted to like MSP430, but I failed. My biggest grief: horrendous datasheets that document the common architecture without giving a slightest hint about your specific device. You want to know which pin does what? You have to find at least 3 papers for that. No hyperlinks! You really needed this timer_A 2? Oops, turns out that your particular does not have this peripheral that you needed, we have removed it just for )*(& and @#^s! They intentionally cripple their low-end models, always depriving them of some useful oscillator, or a second timer, or USI, or something else. Their DCO is a horrorshow. GCC/mspdebug do not support the newer devices and their own IDE is.. family-safe words fail me. |

You could name Atmel's sam4l series, which is targeted at low power consumption applications.
