Hi,
The Kinetis K family uses the FlexCAN IP which is the same as the CAN module of MC56F84xxx/MC56F82xxx.
The Kinetis has peripheral driver package SDK, you can download the SDK package from the link:
Welcome | MCUXpresso SDK Builder
The SDK package can be based on MCUXpresso, Keil, IAR tools and Windows OS.
Hope it can help you
