Hello, does anybody know a more powerful Atmel AVR pendant? Is there any 32bit controller that can make a LED blink with only controller, battery, resistor, LED? thanks very much Paul
ready to run 32bit controller

Do you mean a controller for which you have to provide no development system or software, no programming device, or power supply regulator? Then there's the whole question of why one would specify a 32-bit controller to blink a LED. If you want a 32-bit controller that can blink a LED and do a LOT more go to www.beagleboard.org.

The real question is why the fuck do you think you need to do 32 bit math to blink an LED? Want a flash rate measured in years between flashes? An 8 bit controller will do that too given the onchip program space of even the smallest ones.

If so: Yes. Even 64Bit :-) -- 42Bastian Do not email to bastian42@yahoo.com, it's a spam-only account :-) Use <same-name>@monlynx.de instead !

They use an ARM thumb-only core and come in pretty small packages -- I'd be mildly surprised if they wouldn't run off of an internal oscillator. TI probably indexes them under "ARM Cortex" or something like that. Ditto Microchip, and their PIC24 parts (which are really 32 bit processors, AFAIK). -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

TI probably indexes them under "ARM >Cortex" or something like that.Yes, some (all?) of them have a (lousy) internal oscillator (+/-30% accuracy for the LM3S8962) A lot of them _require_ external parts for internal LDOs (maybe just a cap) and that sort of thing, some even have/had an external (passive) RC filter for the PLL.>Ditto Microchip, and their PIC24 parts (which are really 32 bit >processors, AFAIK).16-bit, actually. I'd suggest looking at the Cortex M0 parts, as they are more aimed at small systems. NXP has some with calibrated oscillator and no separate core power supply. Cheap (< $2 in small quantities).

That's 32Bit with 6 GPIOs. -- 42Bastian Do not email to bastian42@yahoo.com, it's a spam-only account :-) Use <same-name>@monlynx.de instead !

Energy Micro claim 1.8-3.8V Vcc range, in small packages. NXP mention 1.8-3.6V on the LPC11xx Nuvoton have some Cortex M0's in rollout, that claim 2.5-5.5V - nice to have a low end 32 bit, that is PowerMOSFET compatible !! Their tools/boards roadmap looks comprehensive, see http://www.nuvoton.com/NuvotonMOSS/Community/ProductInfo.aspx?tp_GUID=3Da68= a8126-3bb5-4f7a-b6af-aac049dc79a4 -jg
