An electronic circuit with programmable terminations includes a circuit block, signal pads coupled to the circuit block, programmable termination circuits each associated with a corresponding one of the signal pads, and a reference circuit operative to generate one or more control signals for application to the programmable termination circuits. A given one of the programmable termination circuits is configurable independently of at least one of the other programmable termination circuits into one of a plurality of termination states. Preferably, the programmable termination circuits are each independently configurable to provide a particular termination resistance and a particular supply terminal connection type for the associated signal pad. The invention is particularly well suited for use in integrated circuit applications, such as, for example, those involving FPGAs, FPSCs and ASICs.
