Ti120 I/O Banks

Efinix FPGAs have input/output (I/O) banks for general-purpose usage. Each I/O bank has independent power pins. The number and voltages supported vary by FPGA and package.

Some I/O banks are merged at the package level by sharing VCCIO pins, these are called merged banks. Merged banks have underscores (_) between banks in the VCCIO name (e.g., 1B_1C means VCCIO for bank 1B and 1C are connected). Some of the banks in a merged bank may not have available user I/Os in the package. The following table lists banks that have available user I/Os in a package.
