2.5 Introduction to the I/O BANK
There are nine I/O Banks in the GW2AN series of FPGA products, as
shown in below.

This manual provides an overview of the distribution view of the pins in
the GW2AN series of FPGA products. Please refer to 3 View of Pin
Distribution. Different IO Banks in the GW2AN series of FPGA products are
marked with different colors.
User I/O, power, and ground are marked with different symbols and
colors. The various symbols and colors used for the various pins are
defined as follows:
” ” denotes I/Os in BANK0.
“ ” denotes I/Os in BANK1.
“ ” denotes I/Os in BANK2.
“ ” denotes I/Os in BANK3.
” ” denotes I/Os in BANK4.
“ ” denotes I/Os in BANK5.
“ ” denotes I/Os in BANK6.
“ ” denotes I/Os in BANK7.
“ ” denotes I/Os in BANK8.
” ” denotes VCC, VCCX, and VCCO. The filling color does not
change;
” ” denotes VSS. The filling color does not change;
” ” denotes NC;
” ” denotes dedicated pins EXTR.
