High temperature CAN controller

Brian Weber
Prodigy 20 points

I am interested in implementing a CAN bus on an MSP430 in a harsh environment, with 200C temperatures. I have found numerous CAN transceivers such as SN65HVD233-HT and SN65HVD1040-HT that fit the bill, but am having no luck finding a suitable CAN controller.

I know there are a few temperature rated MCUs/DSPs that have built in CAN, but they are nearly 10x as power hungry as the 430 I'm currently using, so I'd rather just add the CAN functionality through an SPI interface or similar instead of changing processors. I would probably be looking for something similar to the MCP2515. Is there such an animal?

    Hi Brian,

    Unfortunately, I'm not aware of any better options available at TI for a high-temperature CAN controller. You may want to try posing your question on an MCU or DSP forum, though, to see if they have some recommendations.

    Best regards,
