MSP430FR5969: Recommended most similar non radiation hardened MCU for development purposes

Kevin John

Part Number: MSP430FR5969


We're looking at this processor for orbital application, and I wanted to know, for development purposes, if the only difference between the MSP430FR5969 and MSP430FR5969-SP the application of the radiation resistant plastic packing? Or, I suppose another way to ask the question would be: is the MSP430FR5969 the processor you would recommend for prototyping devices for in low radiation conditions?

Thanks

    Hi Kevin,

    No, the MSP430FR5969-SP has more features:

    Radiation-Hardness Assured

    • Extended Temperature Operation (–55°C to 105°C) (1)
    • Single Event Latchup (SEL) Immune to 72 MeV.cm2/mg at 125°C
    • Radiation Lot Acceptance Tested to 50 krad
    • 48-pin VQFN Plastic Package
    • Single Controlled Baseline
    • Extended Product Change Notification
    • Product Traceability
    • Extended Product Life Cycle

    Winter, 

    Thanks for the reply. I understand that the radiation hardened processor comes with a suite of features designed to allow it to operate in harsh environments. Could you comment on the other part of my question on whether the standard  MSP430FR5969 (in the VQFN package) would be the appropriate proxy for development purposes for the MSP430FR5969-SP? Should I expect any functional differences between the two models in things like boot-loader operation, or register locations, etc? Should I expect code written for the MSP430FR5969 to execute without modification on the MSP430FR5969-SP? 

    Thanks,
    -Kevin

    Kevin,

    Yes, the standard MSP430FR5969 (in the VQFN-48pin package) would be the appropriate proxy for development purposes for the MSP430FR5969-SP. There are no any software functional differences between the two models in things like boot-loader operation, or register locations, etc, except for Capacitive touch IO support. The MSP430FR5969-SP doesn't support Capacitive touch IO. So, the code written for the MSP430FR5969 is fully compatible with MSP430FR5969-SP except for Capacitive touch IO.

    Just what I needed. Thanks Winter.
