Title: Fully programmable and configurable application specific integrated circuit

Abstract: A method and apparatus for a fully programmable and configurable application specific integrated circuit (FPCA). Programmable I/O cells are programmed for selected electrical characteristics, including power and ground. The circuit contains a functional core for programming the circuit, programmable I/O leads to connect to the programmable I/O cells, and programming logic and control for programming the functional core and I/O cells. Certain leads double as programmable I/O leads and programming control leads, and are used to communicate with the programming logic and control and the I/O cells. A method of programming the FPCA comprises the steps of asserting the programming control signal; applying programming voltage and ground to a respective two designated I/O cells' leads; isolating a plurality of the I/O cells from the programming signal; and programming an FPGA array in addition to the isolated I/O cells of the circuit.
