While looking for other things, I came across this.

(not my f= inal choice for a name btw!)

I wanted to combine at least two functi= ons into the usb stick, they would be:

* gps/time with supercap backup
* other sensor support (wind cups, p= recipitation, barometer, etc)
* some sort of direct output= signal (can bus? spi bus? don't know yet)
* randomness/entropy generator

While my in= itial choice for the former two features would be the ublox device already = discussed, I haven't pursued the possibility of being able to modify th= eir firmware to do what I want. I should contact them I guess... but I'= m wagering that gaining access to that firmware will be difficult, so inter= facing with a cheaper gps device (e.g plaine jane) and adding a microcontro= ller to it seems like the best option.

The problem is I'd like to find something capable of 480Mbit transf= ers.

The first microcontroller I picked (the atmel) seems to be near= end of life and only does 12Mbit, so I went looking for the sexy and new (= a lot of those!), and stumbled across this one:

http://media.freescale.com/phoenix.zhtml?c=3D196520&p=3Dirol-newsArtic= le_print&ID=3D1671968&highlight=3D

I couldn't help but laugh when I saw:

"Linear 4 GB addr= ess space that removes the need for paging, reducing software complexity and ensuring a more 8-bit-like user experience&= quot;

Yea, that 8 bit-like user experience. That's what I want i= n a 32 bit 4GB capable architecture.

The last p= hrase was removed from the official site later, after whoever wrote the pr = release came down off of whatever he/she was smoking.

This chip is WAY too new to consider using, but it is a sign of things to c= ome. Still trying to find a sane 480Mbit USB interface that's under 10 = bucks...
