Is there a table summarizing the differences of CPUs supported by Arduino? What's the lowest power Atmel processor that can be used with an Arduino?

  • This is certainly a programming-related question. I'm writing an Arduino program and I need to make sure that my program will run on all Arduino platforms. – Mark Harrison Nov 21 '11 at 23:41

Perhaps these are too obvious:

The official hardware page might be what you're looking for; clicking on any version brings up an overview which elaborates on each variant. There's also a list of official hardware on Wikipedia, although it might not be as up to date.

The lowest voltage for any official Arduino MCU is, as far as I know, 3.3 V. I'm not sure about the current; the forum thread Minimizing power consumption seems to elaborate further.

(Update by mh) Based on the table above, the lowest power Arduino-supported chip is the ATmega168 with 16 KB flash and 1K SRAM.

  • garmen, the Processor column under "Aruduino Board Models" is just what I was looking for... thanks! – Mark Harrison Nov 21 '11 at 20:56
  • The chart with the Processor column has moved to [List of Arduino boards and compatible systems](https://en.wikipedia.org/wiki/List_of_Arduino_boards_and_compatible_systems). I was looking for the same thing as Mark. – Trygve May 01 '17 at 17:42
  • Thanks for that info Trygve - I updated the link in the answer. – gamen Aug 16 '17 at 10:28
