MSP432E401Y: migrating from 401R series to 401E series MSP432

sam gav

Part Number: MSP432E401Y

Dear TI_experts:

I have a question regarding migration from MSP432P401R to MSP432E401Y.

1. To what extent can I expect code compatibility when migrating? Low/medium/high

2. Is there any summary documentation that tells upfront about the certain minimum changes that must be done to the code and to the use of various libraries when migrating? ( I'm already comparing the datasheets)

3. The operating voltage limits (min-max) between the two seem to be different. Has anyone seen any impact to functioning of any blocks or peripherals due to a narrow operating voltage band in E series compared to R series.

It will help immensely if TI experts help with the above queries, especially question number 2. It will guide us in determining the total overhead involved in migration.

Thanks

Sam

Hi Sam,

If you're using TI Drivers, there should be high compatibility between the two. If you're using anything else, there would be low compatibility. Regarding the changes you must make to the code/libraries, I would refer to these 2 threads for general tips [link1, link2]. While both of these threads deal with migration from MSP432P401R to MSP432P4111, the guidance in these threads may also be helpful in your case.

Thanks,

Urica Wang
