  • TCAN4550: The EOS issue for TCAN4550

    Part Number: TCAN4550 Hi, Our end customer feedback there are 4pcs(Total 100pcs) TCAN4550 is failure and they need to know the result; The below is our schematic diagram and impedance test form, and please advise if there are any error for our design…

  • TCAN4550: TCAN4550 nINT state after RESET

    TI Thinks Resolved
    Part Number: TCAN4550 When TCAN boot up or start, nINT is Low or High by default? Our test shows MCU reads nINT1 and nINT2 as 0 after RESET, which is already interrupted. Is this correct? So FW should clear the Interrupt state over SPI during initialization…

  • TCAN4550: tcan4550 Overwrite and Blocking mode

    Part Number: TCAN4550 Hi Team, My customer uses TCAN4550 and sets RX0 FIFO to overwrite mode. Occasionally, they met errors in the messages transmitted from TCAN to the MCU via SPI. However, once the RX0 FIFO is set to blocking mode, this issue disappears…

  • TCAN4550-Q1: TCAN4550 IBIS Model

    TI Thinks Resolved
    Part Number: TCAN4550-Q1 Other Parts Discussed in Thread: TCAN4550 Do you have an IBIS Model for the TCAN4550? I'd like the CAN bus pins and SPI Bus pins if possible.

  • TCAN4550: TCAN4550 with 3.3VIO and 5V Supply In Test Mode 1

    Part Number: TCAN4550 In reading the datasheet, and using the TCAN4550 in SPI and M_CAN Core Test Mode with an external transceiver, 5VDC on Vsup will not allow the device to participate in SPI and CAN commnication. Is this a correct assumption? Thanks…

  • TCAN4550-Q1: Query on TCAN4550 Interrupt Handling for RX Communication

    Part Number: TCAN4550-Q1 Other Parts Discussed in Thread: TCAN4550 Dear Team, We are using the TCAN4550-Q1 module with the i.MX93 processor over SPI. We would like to understand the behavior of the interrupt pin during RX communication. In our current…

  • TCAN4550: TCAN4550 AP under WIN10 or WIN11

    TI Thinks Resolved
    Part Number: TCAN4550 Other Parts Discussed in Thread: BOOSTXL-CANFD-LIN Hi sir, Do we have TCAN4550 AP under WIN10 or WIN11? Customer wants to test. Thanks a lot!

  • TCAN4550: TCAN4550 Maximum Frame Rate Inquiry and Test Results

    Part Number: TCAN4550 Subject: TCAN4550 Maximum Frame Rate Inquiry and Test Results Hi, I hope this email finds you well. We're testing the TCAN4550 on our custom board with the TCAN4x5x Linux driver and have some questions about its maximum achievable…

  • TCAN4550-Q1: TCAN4550-Q1 silent mode

    Part Number: TCAN4550-Q1 Hi, We are using TCAN4550-Q1 and would like to know how we can configure silent mode? We were not able to find this in the datasheet/documentation. Thanks Best regards, Stefan

  • TCAN4550-Q1: SPI communication issue while reading deviceid of TCAN4550

    TI Thinks Resolved
    Part Number: TCAN4550-Q1 Hi Texas, I am facing an SPI communication issue while reading data from an SPI slave device. During transmission, I can clearly see SCLK and MOSI toggling correctly, and MOSI is sending valid data. However, on the MISO line…
