TCAN4550-Q1: Can SPI output sensor be directly interfaced to TCAN4550-Q1 to get CAN output

Part Number: TCAN4550-Q1
Other Parts Discussed in Thread: TCAN4550

Tool/software:

Hi,

I would like to know if a sensor with SPI output (like an accelerometer) can be directly interfaced with TCAN4550-Q1 to convert SPI to CAN or is there a need for an additional microcontroller

Thanks and Regards,

Ranjith

Hi Ranjith,

While I don't know anything specific about the sensor output, I don't believe this is possible and the TCAN4550 will automatically create CAN messages from a stream of data coming from a sensor output.

I would recommend reviewing the following documents for more information on how to create CAN messages.

Bosch's MCAN User's Manual (Link)

Jonathan

Thank you for the reply!

I am a bit confused , did you mean to say it is NOT possible and TCAN4550 will NOT create CAN messages from a SPI output sensor.

Hi Ranjith,

I apologize for the confusion and typo. The TCAN4550t will NOT create CAN messages from the raw SPI data coming out of a sensor. It will require an MCU to format the sensor data into the required CAN message format.

Jonathan
