Customer is looking for the replacement for TJA1145T, but TCAN1043 does not have the SPI feature. Could you please help further check it? Thank you.

    Hi Aki,

    Our equivalent device would be TCAN1145. There are two other variants, TCAN1144 and TCAN1146, which offer different feature sets. See page 3 on the datasheet for a feature table of these three devices.

    Note that while these are all pin-to-pin compatible with TJA1145T, there are some register differences between this and TCAN114x's. 

    Regards,
    Eric Schott
