    PSoC4 Lin transceiver

    mizo_4684936

      Hello everyone,

       

      I am designing board including PSoC4200M (CY8C4246AZI-M443). The interface I will be using is LIN, I have seen that it's UART pins have support for that. The transceiver I decided to use is NXP TJA1028, which will also power the MCU mentioned above (3v3 and 5V are available). My question is what are UART logic levels? Is it 3v3 or 5v, I can't find anything about it in datasheet. Does it depend on power supply? If so which is better. Also can someone advise what value  pull-ups on tx and rx pins of transceivers should be and why?

       

      Thanks in advance,

      MichaƂ
