It seems that the two most common CAN controllers are the SJA1000 (Parallel Bus) the MCP2515 (SPI).
Are there any alternatives to these parts? Once upon a time, there used to be a Bosch CC770 and an Intel 82527, but I haven't heard any references to these in a long tme.
I'm looking for something to interface to the XMEGA (still specifying the exact model, choice may be dependant on CAN controller) rather than going back to the ATCAN90 series.
Are there any other options I should be looking for?
