Hi
I have a atmega328p running [ur=https://github.com/grbl/grbll]GR.... For that kind of operation that use a lot the timers should I be able to run the atmega328p at 16mhz with a 3.3V?

Thank you

You are out of spec. So I would not make 10000 units.

However, in practice, the ATmega328P will work fine at 16MHz and 3.3V
Especially if you are running at normal room temperature.

David.

Touched on in this thread:

... and discussed many times before. In particular

What does the datasheet chart indicate?

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

The datasheet give the following equation: Freq = 5.6*Vcc - 5 which gives 16 = 5.6*Vcc - 5 <=> Vcc = 3.75

So i think i should keep the 5V power source.

No problem, it is within spec.

No RSTDISBL, no fun!

It is when you specify 16mhz and not 16MHz ;-) (Brutte's point).
