Can LPC55S0x CANFD support 1Mbps (arbitartion stage) and 8Mbps(data stage)

Hi NXP,

Can LPC55S0x support 1Mbps in arbitration stage and 8Mbps in data stage ?

I can't find in LPC55S0x datasheet.

Thanks very much.

Hi Harry,

Got it.

Thanks.

Hi @jimmyli

Yes— the LPC55S0x CAN-FD controller can be configured for 1 Mbit/s arbitration and 8 Mbit/s data , provided the MCAN functional clock is 96 MHz and the external CAN-FD transceiver and physical network support 8 Mbit/s.

The reason this is not listed directly in the datasheet is that the bit rates are derived from the MCAN clock and the NBTP / DBTP timing registers rather than specified as a fixed maximum. The CAN clock can use main_clk with CANCLKDIV = 0 (divide-by-1), and the LPC55S0x maximum clock frequency is 96 MHz.
