Brian,
I took your post and gave it the correct subject, you get a better
chance of answers this way.

I can only comment on the Philips LPC2294 and LPC2194, both with 4 CAN
channels. Have a close look at the CAN Erratas (not fixed but Philips
promised to have fixed devices out in Q2/06). The Erratas are not too
much related to a gateway application more to a simple full-CAN usage.
The filtering options and cross communications between CAN channels is
superior in the Philips implementation, nevertheless, I agree that the
Erratas should be fixed. 
Also, the Philips device runs the fastest from Flash as far as I know.

Hello all!,

I am starting a project that is basically a CAN bus router/gateway. I
was looking at ARM MCUs that have 3-4 CAN channels on them. Here is the
list/questions right now:

Freescale MAC71xx MCUs - 4 CAN bus channels - Anyone used this part
before?? Any pitfalls????
Philips LPC21xx MCUs - 4 CAN bus channels - Has Philips fixed the
CAN issues explained in the errata on the current mask sets????
TI TMS470xxx MCUs - 3 CAN bus channels - Anyone used this part
before?? Any pitfalls????

I guess I could go with multiple single/dual channel parts and communicate
to a "Master" MCU for arbitration/routing of the CAN bus messages.

Thanks,
