What do you want to do with the FPU?
You can get the SAM9263 with CAN nowadays.

Hi Ulf - the reason I want an FPU is that I'm tons and tons of
floating point math. I'm currently using an AT91SAM7X256, but as I
increase complexity I suspect I'm going to run out of CPU cycles. It's
mostly just algebraic functions and trig right now.
SAM9263 runs at 200-240 MHz.
Should give you a lot more performance AND a CAN bus.
SAM9260A will run at 350-400 MHz.
I'm also somewhat worried about using Atmel ARM parts - I've heard
that there's been alot of turmoil in the ARM division, more so than in
other divisions and that it isn't particularly stable right now.
Atmel has never had an "ARM" division. There has been
an ASIC division which sold ASIC, ASSPs and AT91.
The AT91 is moved to the microcontroller division
which means that instead of sharing resources with
the ASIC guys, they are sharing reasons with the AVR guys.
Have you considered the AT572D740? ARM7 + 1 Gflops?
