Hi,
Yes.
It will do the same as it does when the developer of the PCB assembles it: nothing.
But if you treat it the same as the PCB developer - and program it with the firmware - then it will work as desired.
You may buy an empty bottle ... the same does the brewery.
The brewery fills it with beer ... you need to do the same...before you can drink it...

You asked the identical question about a PLD.
Both are programmable, empty devices when you buy them.
