  • Programmable input/output circuit
    Patent number: 8558578
    Abstract: A programmable input/output circuit includes a programmable output circuit configured to drive an output signal to an input/output pad at a plurality of voltages, at least one of the plurality of voltages being supplied by an external circuit. The programmable input/output circuit further includes a programmable input configured to detect an input signal from the input/output pad at the plurality of voltages. The voltage levels of the input and output circuits may be independently and dynamically controllable.

  • Overvoltage resistor and method for its manufacture
    Patent number: 4996512
    Abstract: An overvoltage resistor formed in the substrate semiconductor material of an integrated circuit. The overvoltage resistor is formed from a resistive layer formed over a well of a semiconductor material having a conductivity type which is opposite to the conductivity type of the substrate material. The overvoltage resistor is not connected to the voltage supplies of the integrated circuit, thereby eliminating the virtual pn-diode which would otherwise be formed between the well and the substrate and allowing the overvoltage resistor to protect the integrated circuit from voltages outside the range of supply voltages.
