MSP430F2481: MSP430F2481TRGCT target socket board?

Part Number: MSP430F2481
Other Parts Discussed in Thread: MSP-TS430PM64, MSP-FET,

One of my lab member gave me "MSP430F2481TRGCT" and I just cannot figure out how to program it.

Any assistance would be greatly appreciated.

1) To program it through JTAG, I just bought "MSP-FET430UIF".

2) For target socket board for "MSP430F24xx", TI documents recommends "MSP-TS430PM64". However, the product page says it only works for PM packages. (not for RGC packages I have)

3) I want to avoid programming on final product because doing that means the product has to have bigger footprint for connectors.

4) Is there any appropriate target socket board, or universal approach for this MCU?

Thanks in advance,

Hwang

  • Hello Hwang,

    Welcome to E2E. Thanks for your detailed post and for adding a detailed subject - that really helps our community.

    That's a good start although we recommend the newer MSP-FET over the older MSP-FET430UIF. It may still work but just keep this in mind for future development.

    Thanks for checking our documentation! You're correct, the target board only supports the PM package type for the MSP430F2481.

    For production programming, you could leverage the bootloader (BSL). You can learn more at the following page.

    For your development, I would recommend that you purchase the target board for the PM package and order some MSP430F2481 devices in that package. When you move to your prototypes, you can keep the JTAG circuitry as the target board for any final debugging. Then, when you move to the final product stage, you could use the BSL to program the device (can't use it for debugging) but bring out the 2-wire JTAG SBW lines to a header (or holes for a header) in case you need to debug the final product. If that's not necessary, just use the BSL.

    Hope this helps.

  • Just read through your comment for several times, and studied about BSL for a day.

    Indeed BSL approach is to-go for these general cases, making even smaller PCB footprint.

    But I decided to get similar family products which are supported by target socket board for my specific purpose.

    (Boss says our project needs to be minimal in size, so no external connecters are allowed here.)

    Your advice gave me further insights about MSP430 devices and I saw great potential in MSP430.

    Thank you, you taught me something and changed my life.
