MSP430G2433 32 QFN use with LaunchPad

Other Parts Discussed in Thread: MSP430G2433

All:

I'm starting a development project using the MSP430G2433IRHB32.  I'm using the 32 QFN version, because I need the extra 8 I/Os.  The website lists the launchpad as the development platform for this device, but it will only hold a 20 pin DIP device.  Does anyone have any recommendations for an adapter of some type, or any other development platform I could use to allow me to use the correct, fully functional device?  I prefer to go ahead and start my SW development before my own PCB is ready...

Thanks in advance for your help.

    Hi Adrian,

    You can always debug on the 20-pin MSP430G2433, since all the peripheral registers are the same. Only thing missing would be to actually see the input/output for the 8 additional ports, but verifying the IO part should be trivial once you get your own boards.

    Alternatively, you can always hook the QFN chip to the Launchpad "dead bug" style; you really only need VCC/GND, the TEST/RST for Spy-by-Wire, and optionally whatever IO you want to test.

    Hope that helps.

     Hi Adrian, no UIF adapter from TI is in the development list so you can try build your own small PCB qfn to dil or see offer from ebay:

     Programming QFN Adapter to DIL

    PCB adapter

     Consider the shipping time of these or check at Digikey or Mouser the proper adapter to prototype your circuits and have if faster.
