Abstract
Apparatus for configuring input/output signal levels of interfacing logic circuits operating at different voltage levels comprises: a logic circuit for operating at a first voltage level; a bank of input/output gates coupled to the logic circuit for interfacing input/output signals at a second voltage level, different from the first voltage level, to the logic circuit, the bank of gates including a port for setting the operational voltage level thereof; and a control circuit coupled to the port and governed by a control signal to configure the operational voltage level of the bank of gates to render the logic circuit and the interfacing input/output signals voltage level compatible.
