Now I would use 100pin-MSP430F674x.
In product folder, It it recommend to use 128pin socke, not 100pin.
And Checking the Hardware tools user's guide,it is likely that PZ100B can be supported F67xx.

It was actually able to write and load with suitable jumper setting(AUXVCC).
Is it correct?
Can F674x be used for PZ100B?
