I have briefly used CAN on the Infineon C505C microcontroller. It has a good compliment of peripherals - ADC, capture/compare regs, CAN, watchdog. The biggest downside is it is only available in ROM/ROMless/OTP, no flash!

One upside of the Infineons is that Infineon has a program called DAvE that writes Keil and Tasking C templates automatically. It has a GUI that allows you to setup the hardware by automatically writing code templates. I very rarely have to look in the C505C manual for details on reading and writing registers. It also provides functions for using all the peripherals. It saves quite a bit of time.

The only problem is that you become a slave to the Infineon product line if you never get off your lazy bum and read up on the hardware.

My next CAN project is going to be based on a Cygnal C8051F04x microcontroller. I think the high performance and onboard ISP flash will prove to be more useful for one-off projects than the Infineon products.

The Infineon parts seem to be more suitable for OEM devices, however. The lower cost and wider temperature range of -40 to 125 is ideal for automotive embedded hardware.
