TCAN1044A-Q1: WUP on this device

Part Number: TCAN1044A-Q1


Hi team,

Is it possible to use WUP on this device at 500kbps, 1Mbps, and 5Mbps of the data rate?

Best regards,

Shunsuke Yamamoto

  • Hi Shunsuke,

    Please help see section 8.4.3.1 of the data sheet clarifying 500kbps and 1Mbps works, but not 5Mbps.

    I.e. " The ISO 11898-2:2016 standard has defined times for a short and long wake-up filter time. The tWK_FILTER timing for the device has been picked to be within the minimum and maximum values of both filter ranges. This timing has been chosen such that a single bit time at 500 kbps, or two back-to-back bit times at 1 Mbps triggers the filter in either bus state. Any CAN frame at 500 kbps or less would contain a valid WUP", thanks.

    Best Regards,

    Michael.
