MSP432P401R: Upcoming Rev D MSP432 micros & MSP432Ware

MSP432P401R: MSP432 REV C TO MSP432 REV D

Part Number: MSP432P401R

Hello,

This is a question regarding MSP432 Rev C  and its compatibility with the upcoming  MSP432 Rev D micro-controller. Our main concern is that the new Rev D micro-controller will not be compatible with MSP432 Rev C.We have finished our R&D phase with Rev C and started production with Rev C.Everything is fine with Rev C but in Rev D I have noticed that SD card initialization problem as it related to Spi.Does it because of some Spi module upgradation in Rev D or Problem with Mspware compatibility?This would be a risk on our end since we are just now beginning production and have already completed a host of reliability tests with             Rev C micro-controller running MSP432Ware. We have ordered a reel from mouser and We have received Rev D from there.Can I get Rev C from Texas instruments store if any urgency is there and any issue is not solved in Rev D from our side.

Regards,

Pratik Debnath

    Pratik,

    thanks for bringing this up here. FirstI have to say that it is not possible to order dedicated DIE revisions at TI. Normally TI only delivers the latest revision.

    So far it's not clear if the fix of USCI48 has an impact. I checked the ERRATA sheet (SLAZ610Q) and found also BSL16 and SYS26 be fixed on RevD.

    So the SD card related problem is application specific can you comment if it uses SPI interface or might be affected by the other 2 ERRATAs.

    Also it would be interesting if all RevD parts show the same behavior.
