SelectIO Resources General Guidelines

This section summarizes the general guidelines to be considered when designing with the
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.
banks. UG475: 7 Series FPGAs Packaging and Pinout Specifications includes information on
the I/O banks for each device/package combination.
