In MSP430F54xx family of devices that I've spent most of the last year
working with, the smallest MSP430F5418 has 16KiB ram, 128K flash, while
the largest MSP430F5438 has 16KiB ram, and 256KiB flash.
Arduinos have 32KB flash and 2KB RAM, and support WIFI and IPv4 (including
DHCP, DNS, UDP, TCP, and a small web server).
I am working with Arduino devices and there are obviously different types of
types available.
Yes, though currently available models don't vary widely on memory.
I use the http://arduino.cc/en/Main/arduinoBoardUno and it has the
32Kb flash and 2KB of RAM. There are versions that different hardware
properties.
Most of the variation is around I/O pins, processor speed, and physical
layout - again, based on currently available models.
The Uno, e.g., uses the same processor on the Duemilenove (the basis of
the Diamondback I use) and varies only in how USB is supported.
It is interesting to note that I couldn't find an IPv6
implementation for Arduino and, depending on your application needs,
the available ram and flash may not be sufficient.
I typed in "ipv6 arduino" and found a stack fairly easily.
It does rely on an ethernet shield that itself implements ethernet, and
has 8KB of packet memory. It includes a small web server as an example.
The WIFI shield on the device I use has hardware support for crypto, too.
