Microcontroller Recommendations for Custom SPI to CAN 2.0 Conversion Project

Hello

I'm doing a project in which voltage and current measurements are needed to be converted to CAN 2. I'm searching for a microcontroller that do this task in the simplest possible scheme. voltage measurement board is a special chip and requires to be controlled by some specific set of commands. So, I cannot use options like MCP2515 and need to choose a suitable microcontroller. Do you guys have any suggestion? If yes please let me know as I need to make a decision very fast.

Thanks,
Mahmoud

Most microcontroller families have support for the CAN bus, usually you have to look for a specific part within a family, and SPI is universal.
It probably comes down to what processors you have used in the past. IF you have used any, then go to the manufacturers web site of the family you have used and look up their micros, usually there will be tables with a display of the peripheral support.
If you haven't used micros before, then you have to decide if you want to use 8 or 32 bit processors, and you need to look at the development support, perhaps a ready made board, and the programming tool chain.
If 8 will do it, Microchip for example have the PIC and AVR families, do a search on 'AVR support for CAN 2'' and 'PIC support for CAN 2' and see what you turns up.
As for ARM, again many manufacturers, try ST Semiconductors.
