Re: PIC vs AVR vs ARM

We have used AVR MCUs in many of our products and were very happy with
them. On a new project I decided to take a look at the ARM MCUs to see
if we could branch out from some of the limitations of the AVR. We did
a very exhaustive comparison between the various ARM processors and the
ATmega128 and found that the ARM chips were generally lower power,
lower cost and fit in a smaller footprint on the board. We also were
able to use a much smaller crystal.

The ARM we chose for this project was the AT91SAM7S64 due to its
combination of low cost and low power. The Philips parts seem to run a
close second and may even beat the Atmel SAM7 parts depending on
exactly the combination of features you need. If you don't need the
lowest power then the other brands of ARM chips could be considered, ST
Micro STR7, TI TMS470 and Analog Devices ADuc7 among others.

Did you check out the feature comparison chart at www.gnuarm.com?
Click to the Resources page and scroll down to the ARM chips section
where you will find three different links for the comparison chart.

To add to this question, I've been doing mostly AVR work and I'd like to
branch into ARM. I had planned on just picking up some of Atmel's ARM
gear, but would anyone suggest any other first leap friendly ARM procs?
The Luminary has already been mentioned and seems interesting.

Hi All,

As an amateur embedded circuit player, I have used couple of AVR and
PIC microcontrollers in the past.

In these days it is not to hard to find small, ARM based ready to use
embedded boards under $100. They seems to have faster clock speed then
most of the AVR and PIC boards.

Can anybody shortly compare ARM with PIC ad AVR interms of (a)
performance (b) software support (c) price?

Regards,

Miem
