Discussion Groups | AT91SAM ARM | graph of speed vs power for five brands of ARM7 - available? (Courtesy: Jean Pierre")
For users of the Atmel AT91SAM7 and AT91SAM9 ARM CPU chips. Atmel has taken a new direction by combining on chip flash and ram with the ARM CPU on a single die. This provides low cost devices for small systems using the ARM CPU. This group is to exchange information to help users get started and learn how to use the devices.

Hi,
"jeanpierrepoulin" has written in an email to
A...@yahoogroups.com on 09 Nov 2006 the following:
"have put together a graph of speed vs power for five
brands of ARM7 MCUs. Atmel and Philips seem to have
about the same curve. The ADuC parts have a higher
quiescent with roughly the same slope. The STMicro
parts are high power consumption with a quiescent
power equal to the SAM7S parts full power. The
Luminary Micro Stelaris parts are not fully
characterized yet, but with a 2.5 volt core they are
by far the highest of this group. I did not evaluate
the Oki, TI or any ARM parts from Motorola
(Freescale). I know the TI parts are very high
power as are the Motorola parts. The OKI parts are not
low, and I don't care for them much myself.
I uploaded a PDF copy of the chart to the files
section. It might be worth a look. "
Is this PDF file made by Jean Pierre available on
www.embeddedrelated.com (I couldnt see a files
section)? Or is it available anywhere in the site of
AT91SAM yahoogroups? Would be great if somebody can
give a tip.
Thanks.
