Be amazed how many want to put it through a very SMALL PIC. > Your post was a bit harsh, but it is the truth. Seen a lot of them and if they looked at past posts first on embedded.com they would have seen many times the similar thing said in a lot less harsh terms. -- Paul Carpenter | paul(a)pcserviceselectronics.co.uk <http://www.pcserviceselectronics.co.uk/> PC Services <http://www.pcserviceselectronics.co.uk/fonts/> Timing Diagram Font <http://www.gnuh8.org.uk/> GNU H8 - compiler & Renesas H8/H8S/H8 Tiny <http://www.badweb.org.uk/> For those web sites you hate

Running at 200 MHz with built in cache, it should run in circles around the Cortex parts. Can be had in a TQFP package. If you want to go the lower cost approach, the SAM3S also have sort of a sensor interface. If can do DMA from parallel I/O An AVR32 will have higher processing power than the Cortex-M3, due to its DSP featured instruction set. The ATXMEGA64A1 has DMA and Event system, as well as an external bus, so you can add large external memory to this AVR.
