Microcontroller Capability Trend for Automotive

David Lim
Prodigy 30 points


Dear All,

just want to post a query on the current technology trend for automotive microcontroller. To my understanding, currently Freescale has products that able to link up to FlexRay protocol. So, what will be the future trend and also does TI has any of those chips ?

Welcome all feedback.

    David,

    TI's Automotive MCU group is working with the Flexray consortium and currently has both a stand-alone Flexray controller and Flexray IP integrated into their MCUs.  Unfortunately at this point they only sell directly to automotive suppliers and not the broader market. 

    We have seen additional interest in Flexray outside of automotive (medical and industrial) and are looking at how and when to support with our MCU portfolio.

    I assume you are using a C2000 Real-time Controller.  I'm interested to understand your use case for Flexray.  What's the application? What other communication standards are you already using?  Would you consider an external controller (through SPI port)?  Would Flexray be in all of your systems, or optional?  Would you rather isolate the communications to another processors (ARM based?) and let the C2000 run the control loop?
