Hi
I have build an dev board for xc2s200 (pqfp208) device and use two asm1117 for 3.3v vccio and two asm1117 for 2.5v vccint. now i want to solder the device but i wonder where is the first pin.there is no clue in datasheet and in spartan3 devices it seams that the pin one is located in the left and button of the logo does this apply to spartan II device too. does these two regulators have enough power to power the device.
with best regards.
