New! Which Microcontroller is the best immunity to EMI or Noisy

Hi friends,

I'm planning a microcontroller project which is operating in high EMI or noisily enviroment. Anyone has experience in that area please suggest which microcontroller is the best choice?

Can the uvision simulate random EMI and noise crashes?

thanks,
zorx pak

:) Happy microcontroller programming :}

New! RE: Which Microcontroller is the best immunity to EMI or Noisy

My suggestion is to use microcontrollers with integrated oscillator and as many of peripherals integrated into mcu's package (this depends on your project requirements). Also, wich mcu's have you used (8051, pic, arm, ...)?.

For 8051 family my suggestion is DO NOT USE THE Silicon Laboratory bits EVER . Look on theire site, wide choice, lots of code examples but they dont work with NFRP decoders.

Regards

"...they dont work with NFRP decoders."

You're going to have to give me a clue. What is an NFRP decoder?

"For 8051 family my suggestion is DO NOT USE THE Silicon Laboratory bits EVER"

Ok, they might not work with an NFRP decoder (???), but it seems somewhat OTT to rubbish them all just because of this one failing.

The NFRP decoder is a Near/Far Remote Processor module. We wrote it about 5 years ago in C.

So YOU wrote the NRFP decoder.

Maybe, just maybe, there is something wrong with YOUR code that stopped it working with a SiLab part.

Hardly seems strong enough evidence to rubbish the developments of a whole company, huh?

New! Are you two related?

1) zorx pak asks question
2) kevin dev8 answers and mentions NRFP
3) I ask question about NRFP
4) zorx pak answers question on NRXP saying it's his

Now there's a strange co-incidence!

New! sure they do

sure they do if the design is done with concern for what they are exposed to.

I use SILabs chips in a VERY noisy environment and have zero, none, nada problems.

If you use shortcuts in a 3V3 5V mixed environment, you get what you ask for.

New! NO microcontroller is immune to EMI or Noise

NO microcontroller is immune to EMI or Noise, the name of the game is DESIGN and LAYOUT.

I outlined the criteria here: http://www.8052.com/faqs.phtml?FAQ=119926

If you have any thought about trying this with a cheap design and a 2 layer board, GIVE UP
