Hi team,

I could not decide which MCUs arm based, c2000 or msp430 ? could you explain difference of them in detail.

Thank you very much for your help.

Best regards,

    Almost all C2000 MCUs(with the exception of the F28M35/M36) use the TI proprietary C28x 32-bit CPU core as the main processor with an emphasis on real-time control.  The F2838x device includes an ARM M4 as a co-processor to handle common communication protocols(and supports ARM drivers) to allow the C28x more bandwidth for real-time control functions.

    The MSP430 devices typically use their own proprietary 16-bit RISC core, with a focus on low operational power.  There are some devices in the MSP family, MSP432, that use an ARM core as their central processor.

    In terms of usage, both the C2000 and MSP430 have a large ecosystem of support SW/FW depending on your application need.

    If you are strictly looking for ARM core only, the MSP432 or a Sitara MCU device would be your best bets.

    Best,

    Matthew
