TM4C129ENCPDT: roadmap

Part Number: TM4C129ENCPDT

Hello

I am looking to add new features to a couple of our products which use the TM4C129ENCPDT but am starting to reach limits of flash and RAM.

Before I look to other processors such as STM32 I was wondering what is happening with the TM4C129 family.

We use the TIRTOS which has had no updates since 2016 and the chip itself has had no new variants added and seems to be pretty set at what we currently have.

With the extra memory required to add things like TLS  and VOIP we are looking to other devices which provide the compactness of a single device with the nice features such as USB, Ethernet, SPI, I2C but with more memory.  I know we can add extra external memory, but that defeats the purpose of using a single chip micro.

I saw another post which says TM4C129 is still actively supported and TIVAWARE has been updated, but the TIRTOS and NDK are sitting idle and we already are using LWIP in some of our TIVA devices because the stack has more features and active maintenance.

Can someone tell me if TM4C129ENCPDT is worth holding onto, or should we be looking at alternatives going forward.

  • We cannot comment on unreleased future product. The TM4C129 family is currently being actively marketed and supported. We are in the process of releasing new application notes and user's guides.

  • Hello Barry,

    While I can't give you a direct answer because really you need to assess your options and what is offered to make that decision, I can fill you in on the general background with TM4C right now.

    As you saw, yes the TM4C product family is being actively supported by our team and we will continue to support these devices for many years to come. As Bob mentioned, we are working on new collateral to help make TM4C easier to start designing with for new applications and we understand a lot of these systems will have a long product lifespan.

    TivaWare will continue to be updated as needed and our application notes are aimed to supplement the TivaWare offering such as by adding more advanced examples (one in the pipeline will be covering LWIP). Our objective is to help simply software burdens and speed time to market for customers who find the performance and peripherals of TM4C devices to meet their requirements.

    However, TI-RTOS and the NDK was not something our team had owned before and while we have gained more ownership of that piece recently, currently we do not have a plan to make an update to it. That isn't to say we won't consider it in the future, but it's just a matter of trying to maximize our impact with what time we spend. To that end, I will take note of your concerns with the lack of TI-RTOS updates for the next time we assess next steps to improve our TM4C offering.

    I hope this gives you the information you need to make an informed decision on what is the best path for you moving forward.
