MSP430FG6626: thinking about replacing msp430f5529

Part Number: MSP430FG6626
Other Parts Discussed in Thread: MSP-TS430PZ100AUSB, MSP-FET

Hi all,

I am considering a new design featuring a TI MCU with USB. The current design features a msp430f559 and was wondering about the possibility of replacing it by the newer msp430fg6626. However, some questions come to my mind:

        1) Regarding hardware, is there any development launchpad available for this family? Don't mind if it is a MCU slightly different to fg6626. Otherwise I read we could use MSP-TS430PZ100AUSB development board. How does this differ from a Launchpad, do we need an external programmer?

        2) Regarding software, what are the programming possibilities of this fg6626? I am guessing full baremetal and driverlib support. Is the part fully supported by TI-RTOS as MSP432 is?

        3) Regarding logistics, I noticed there are few units of msp430fg6626 available (digikey). Is there a particular reason for this? Is this part somehow reaching any kind of end-of-life? This part was released in 2018.

Well, please let me know what you think about the 3 questions.

Be safe and have a nice day!

This is part of the data processing stage.

    Hello Kazola,

    Please see my answers below. 

         1) Regarding hardware, is there any development launchpad available for this family? Don't mind if it is a MCU slightly different to fg6626. Otherwise I read we could use MSP-TS430PZ100AUSB development board. How does this differ from a Launchpad, do we need an external programmer?

    There is not an EVM available for this device. The MSP-TS430PZ100AUSB is a socketed board which brings all pins to headers and is a good general purpose platforn. This board does not include the eZ-FET, so an external programmer is needed. It does include a 14 pin JTAG header, so you can use the MSP-FET for JTAG programming. If you already have a launchpad, you could also wire up SBW from the eZ-FET on another launchpad.

           2) Regarding software, what are the programming possibilities of this fg6626? I am guessing full baremetal and driverlib support. Is the part fully supported by TI-RTOS as MSP432 is?

    Yes, FG6626 offers bare metal and driverlib support. Examples can be found in resource explorer shown below.

    Section 1.5 of the document below shows the boards and devices that have TI-RTOS driver examples. The FR6xx devices are included, but the example is for FR6989. There are also details of porting to other devices in the same family in this section.

           3) Regarding logistics, I noticed there are few units of msp430fg6626 available (digikey). Is there a particular reason for this? Is this part somehow reaching any kind of end-of-life? This part was released in 2018.

    No, this part should not be near end of life as you noted it is a newer device. I'm not sure why Digikey has low stock. You can also purchase directly from the TI store. There is a good amount of stock available there.
