ready to run 32bit controller

Started by Paul Geisler June 2, 2010
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

Yes. -- Rich Webb Norfolk, VA

Your question is a bit vague. 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.

Using a 555 timer, you should be able to make something flashy for about 4 dollars. (hint: USD 0.25 = 2 bits). --------------------------------------- Posted through http://www.EmbeddedRelated.com

What 32 bit controller can't do that? 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.

He wasn't asking for a quartz, so maybe really wanted to know if there are 32bit controllers that can run w/o such. 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 !

Try the TI/Luminary parts. 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

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.

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).

Hasn't NXP just announced a 8-pin Cortex-M0 part ? 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 !

I presume you allow a decoupling capacitor ? ;) If you are serious about 'battery' and don't want more parts, then you'll need a wide-supply 32 bit core, and that suddenly shrinks the field. 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
