ABSTRACT:
A programmable I/O cell with a multiplicity of configurations and data conversion options implemented through the use of antifuses. Increased logic utilization and reduced number of components necessary to implement such designs by using the registers in the I/O cell to implement data conversion functions thereby saving the logic and registers of the FPGA logic cells for implementation of other functions is achieved. Serial-to-parallel and parallel-to-serial data conversion operations utilize adjacent registers in adjacent cells to perform shift operations.
