Try to put the latest devices on top of each section and mark end-of-line products. Only specify the main parameters of the micro controllers and go more into deep with details about the CAN interface. Always try to put a link to the data sheet or manual.

* PIC18-Q84 Product Family of 8-bit microcontrollers combines an extensive array of Core Independent Peripherals (CIPs) with Controller Area Network Flexible Data Rate (CAN FD) for automotive interface and smart sensor networks. • CAN FD features: – Functional in CAN FD or CAN 2.0B modes – One dedicated transmit FIFO – Three Programmable Transmit/Receive FIFOs – One Transmit Event Queue – 12 Acceptance Masks/Filters.

PIC32MZ EF Press release.
2 MB Flash, 512 KB RAM, 18 MSPS 12-bit ADC, FPU, Crypto Engine, Hi-Speed USB, 10/100 Ethernet, 2xCAN

dsPIC33CK 16bitDigital Signal Controller (DSC) family; 3.0V to 3.6V, -40ºC to +125ºC, DC to 100 MIPS; CAN Flexible Data Rate (CAN-FD) Module ('50x devices only)

dsPIC33CH dual-core micro-controller optimized for motion control applications. The slave core is managing time-critical speed and torque control while the master handles the CAN-FD communications, system monitoring, and diagnostics tasks.

PIC32MZ 32-bit MIPS32 microAptiv Core @ 200MHz, up to 2 MBytes Flash and up to 512KBytes RAM, Two CAN controllers. For bootloaders, this feature seems to be relevant: Live-update allows the flash memory to be updated in the field while application code is still running, all in a fail-safe manner.
Older vesions of the family, like PIC32MX5/6/7 too have CAN.

Microchip was one of the first manufacturers which provided a CAN controller with SPI interface to the local micro-controller.
