MSP432E401Y: Need confirmation on EOL & Support, needs replacement for MSP432P401RIPZ

Part Number: MSP432E401Y
Other Parts Discussed in Thread: TM4C123GH6PM

Tool/software:

Hi team,

We have an industrial product from our customer which uses MSP432P401RIPZ as the main controller.
Since this MCU is now EOL, we are looking for a replacement MCU which can be integrated with minimum hardware and software changes.
We are considering using the MSP432E401Y which looks closest to the currently used MCU, but we need confirmation on the product lifecycle plan and Support for this, as we do not want a redesign again within a few years. This product is going to be a volume production which will go on for next few years, so our end customer needs confirmation on how long this MCU will be in production and supported by TI.

Please confirm on the EOL plan for the MSP432E401Y, or if you have any better alternative MCU from TI as a replacement, Kindly suggest the same. We need the hardware specs same or better than the MSP432P401RIPZ, and require minimal change in software and hardware design for the migration to new MCU.

Thanks in advance!
Regards,
Shawn

      There is no plan to EOL the MSP432E. 

    In general, our process to evaluate whether a device is a candidate for obsolescence is to consistently review device activity and if the situation is merited with limited or no activity for an extended time period, we will move the device to NRND and subsequently offer an EOL LTB following notification for JEDEC practices. 

    There are always exceptions to this process and these are taken on a case by case basis and our goal is to work with customers to find a solution. And again, there is NO plan to EOL the MSP432E at all. You would not need to worry about the longevity of this device.

    MSP432E and MSP432P are not compatible in terms of pinout and neither the software. However, they are both supported by the SimpleLink SDK which provides a level of abstraction. Therefore, if you have been using the SimpleLink SDK for your MSP432P development, much of the SimpleLink peripheral drivers will look familiar to you.

    Hi  ,

    Thank you very much for the clarification regarding the EOL and support for MSP432E401Y.

    The difference in pinout is not an issue as long as we get all the peripherals available in the new MCU. Do you have any recommended MCU's as an official replacement for MSP432P??

    Thanks & Regards,

    Shawn

    Hi Shawn,

      Can you tell me what peripherals and memory sizes (Flash and SRAM) and performance do you require for your applications? MSP432E will have all the peripherals that are on MSP432P401R and more. Another MCU option that you can consider is the TM4C123GH6PM. Please find its product page at https://www.ti.com/product/TM4C123GH6PM

      For Tiva family of MCUs, please use TM4C Microcontrollers Product Selection Guide (Rev. E)

    Hi  ,

    Thanks for the update, we shall proceed with MSP432E as all peripheral requirements are matching.

    Thanks & Regards,

    Shawn
