Abstract: Systems and methods for achieving multiple supply voltage compatibility of an input/output (I/O) ring of an integrated circuit (IC) chip. The IC chip includes a core surrounded by the I/O ring which includes a voltage detector circuit. An I/O supply voltage of the IC chip is sensed by the voltage detector circuit to generate a control signal. The control signal is used to configure the I/O ring to operate at the I/O supply voltage of the I/O ring, thus enabling the IC to operate at multiple supply voltage levels.
