STM32G473 FDCAN pinout contradicting

[Martin Devera]

In DS12712 Rev 2 (STM32G473) table 13 shows PB10/11 as CAN3_TXFD/CAN3_RXFD but in table 12 CAN is not listed for these pins. Also in tab 13 sometimes it is CAN3_TX and sometimes CAN3_TXFD. Which one is valid ?

Interestingly in STM32G474 tab 13 both CAN pinout and naming is different.

​Hello Martin,

This is a mistake in the Table 13.

The table 13 must be aligned with table 12:  CAN_RXFD and CAN_TXFD signals are to be removed from table 13. The FDCAN peripheral has two signals: FDCANx_TX and FDCANx_RX. This is correct in table 12.

G473 datasheet will be aligned with G474 datasheet.

Thanks for the input.

Best regards,

Najoua.
