i bought this from olimex .where i have to give power supply . pin 78 and 80 or any else.
 

See datasheet:

https://www.ti.com/product/msp430fg439


According to datasheet:

AVSS 78 is Analog supply voltage, negative terminal. Supplies SVS, brownout, oscillator, comparator_A, port 1, and LCD resistive divider circuitry.

DVSS1 79 is Digital supply voltage, negative terminal.

AVCC 80 is Analog supply voltage, positive terminal. Supplies SVS, brownout, oscillator, comparator_A, port 1, and LCD resistive divider circuitry; must not power up prior to DVCC1/DVCC2.

The Olimex and Sparkfun ones have the same connections. That's because they're the same board.

So, use the connections mentioned above.

Hope this helps.

this is the shematics of my header board
when i was working in msp430f449 i have shorted avcc and dvcc and gave a supply of 3.4v...then shorted avss and dvss and grounded.This has worked out fine
but in msp430fg439 when i did the same its not working out?
could some one tell me the correct pin to give supply for msp430fg439?
