From: Bill Giovino on 29 Apr 2010 21:23 http://www.microcontroller.com/news/STM8_IAR.asp The IAR Embedded Workbench is based upon IAR's optimizing C compiler, and includes full support for all devices in the STM8A, STM8L, and STM8S families. Evaluation as well as free versions are available. The STMicroelectronics STM8 is ST's low power 8-bit microcontroller. Article includes a comprehensive list of all STM8 devices supported at this time. Bill Giovino Executive Editor http://Microcontroller.com

Makes me wonder why? There are two compilers on the market and both are pretty mature. Both are much lower cost or even a fraction of the cost. In the case of Raisonance, the same user interface RIDE7 supports pretty much every STM device on the market, starting with the older 8-bit (not supported by IAR) all the way to the ARM based 32-bit devices and even the PowerPC based SPC56xx devices. So, if a customer wants a decent compiler that supports the whole STM portfolio, why not using the Raisonance compilers and save a lot of money while doing it? Guess the writer of this article thinks the same: http://tools4cortex.com/the-community/52-stm8s-compiler For information on the Raisonance STM8 compilers check here: http://www.mcu-raisonance.com/~stm8st7-c-compiler__microcontrollers__tool~tool__T018:4cpm5flha55r.html The other mature compiler for the STM8 is from Cosmic.

Oops, hit the send button prematurely http://www.cosmic-software.com/stm8.php Cosmic also supports the ST7 and the ST10 / Infineon 166. Sp another compiler that supports many ST architectures. It lags the support for ARM though, which makes it more difficult to migrate from STM8 to STM32. But that avenue is covered nicely by Raisonance. An Schwob

For a new part? :-) OK the STM8 is a new part in a family of mature parts. >Both are much lower cost or even a fraction of the cost. There is a proverb about accountants who know the cost of everything but the value of nothing. Ruskin also had a comment on it over 150 years ago. http://www.phaedsys.com/resources/posters/PS_Value2_0210.pdf BTW I have just had a client change from a cheap compiler to one 4 times the cost because the cheap one just did not perform and had too many bugs. Which has proved the point and delayed them by several months. > In >the case of Raisonance, the same user interface RIDE7 supports pretty >much every STM device on the market, starting with the older 8-bit >(not supported by IAR) all the way to the ARM based 32-bit devices and >even the PowerPC based SPC56xx devices.

Again they consider cost rather than value. There is a lot more to a compiler than it's cost. I suspect that the reason why ST got IAR to do a compiler for the STM8 is that they wanted a high quality professional system. There is no denying that IAR produce highly professional systems with solid components that can and have been tested to the highest levels. In fact they have been validated for safety critical use at 61508 SIL3 that I know of. -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

It is NOT, neither is the one from Cosmic. Both made by companies with 20 years experience with compilers in the embedded market and both survived the tough time so there must be something they are doing right. Don't get me wrong, I have worked quite a bit with IAR compilers (and Raisonance and Keil for that matter) and the IAR IDE workbench is very powerful. My point was that I am surprised that IAR tries to enter a small nice market that has already 2 reasonably strong players in it. My wild guess, ST has "convinced" them by what means ever to take on the ST 8-bit architecture. After all, ST does not participate n the Cortex-M0 game like NXP. And btw. I would consider a Cortex-M0 based device a direct competitor to the STM8 offering for any new design, just much more powerful. Cheers, the Schwob
