SelectIO resources in 7 series FPGAs.
7 Series FPGA I/O Bank Rules
In 7 series devices, an I/O bank consists of 50 IOBs. The number of banks depends upon
the device size and the package pinout. In the 7 Series FPGAs Overview the total number of
available I/O banks is listed by device type. For example, the XC7K325T has 10 usable
I/O banks. Figure 1-5 is an example of a columnar floorplan showing the XC7K325T I/O
banks. UG475
: 7 Series FPGAs Packaging and Pinout Specifications includes information on
the I/O banks for each device/package combination.
