MSP430FR2422: Reference design for the MSP430FR2422

Part Number: MSP430FR2422
Other Parts Discussed in Thread: MSP430FR2433

Hi - 

I'm looking for an example schematic for using the MSP430FR2422 (particularly the IPW16 package).  

I haven't found anything in the technical documentation that could be used to quickly ascertain the minimum required surrounding components such as whether external clocking options are required, and other items that might affect the overall board area and BOM cost it consumes.

Thanks,
Tom

    Hi Tom,

    I would recommend that you start with the MSP430FR2433 Launchpad:

    https://www.ti.com/tool/MSP-EXP430FR2433

    You should be able to quickly prototype what you need with this platform and your code should be compatible with the lower cost device I recommended.

    You can find code examples on how to use the ADC here:

    Hi Leo -

    Thanks for the pointer to this Launchpad.  I definitely can look into ordering the development kit and prototyping code, etc.   But, right now, the issue is that I'm trying to establish a bare-bones schematic for using the MSP430FR2422.  It's possible that I include as many as 8 of these devices on my board to maximize parallel data acquisition.  The timetable is relatively short to finish our board design and send it off to be fabricated, so it would be a challenge to order the Launchpad Development kit, get up to speed on using the ADC, and then apply that learning to the actual board we're designing.

    Mostly, I'd like to see a simple example of the MSP430FR2422 with a schematic that shows one or more common scenarios with how to hook up each pin and the rationale behind that decision for the application.  Most of TI's datasheets have examples within the datasheet itself that help to Quickstart the hardware design so that the BOM cost and board area can be roughly estimated.  But, I'm struggling to find that in the technical documentation surrounding the MSP430FR2422.

    Is there a reference design for this chip that would help give me a quick start on designing it into my board?

    Thanks,

    Tom

    Hi Tom,

    We don't have a reference design specific to this chip.  We do have a target board which has fairly minimal schematics for what's needed for this chip:

    https://www.ti.com/tool/MSP-TS430RHL20

    You basically need to provide power and ground to the device with some means of programming it(ie. spy-by-wire) if you're not programming the devices before populating them. 

    Let me know if this helps.

    BR,
    Leo
