Are the MK2 UART_RX pins 5V tolerant

Hello,

I have a question about the MK26FN2M0VMI18. Are the UART_RX pins 5V tolerant?

I have taken over a design from an engineer that has left our company. And he has a 5V RS485 signal going to an UART_RX pin.

I do not see in the datasheet that this pin is 5V tolerant.

Thanks,

Pat

Hi Pat,

Sorry for the inconvenience we bring you!
IO on MK26 are not 5V tolerant.
Part numbers that support 5V tolerant will be mentioned in the Data Sheet.

Best Regards,
Robin
