CAN‑FD 5 Mbps Support on S32K146

Hello NXP Team,

I am working with the S32K146 MCU and would like to confirm the maximum achievable CAN‑FD data-phase bitrate.

My setup:

MCU: NXP S32K146 (FlexCAN with CAN‑FD enabled)
CAN source clock: 80 MHz PLL output
Trying to configure CAN‑FD data-phase bitrate = 5 Mbps

Re: CAN‑FD 5 Mbps Support on S32K146

Hi,

chapter 55.3.11.1 Clock domains and restrictions of the device RM shows equations for calculation of max achievable data phase bitrate. The 5Mbps, you mentioned, is possible.
You can use below calculator for bitrate parameter calculation
