摘要: A configurable input device for an integrated circuit having a plurality of input pads, the input device including a plurality of buffers, where each buffer is associated with one of the input pads. Each buffer receives a mode select signal and the buffer is responsive to the mode select signal to place the buffer in an enabled mode or a disabled mode. A receiver portion within each buffer is coupled to the associated input pad. The receiver portion pulls the associated input pad to a preselected logic state while the buffer is in the disabled mode. An output driver within each buffer generates an output signal responsive to a signal on the associated input pad while the buffer is in the enable mode and provides a high impedance while the buffer is in the disabled mode. An output node is coupled to the output drivers of the plurality of buffers.

摘要: An on-chip voltage regulator for controlling a gate of a regulator transistor having a first terminal coupled to receive an external power supply voltage and a second terminal coupled to provide a regulated voltage level to an internal circuit formed on a chip on which the on-chip voltage regulator is formed. The on-chip voltage regulator includes circuitry for detecting when a high current load to which the second terminal of the regulator transistor is coupled is activated. A control transistor is provided having a first terminal coupled to receive the external power supply voltage, a second terminal coupled to the gate of the regulator transistor, and a gate responsive to the means for detecting. In operation, a control voltage with an overshoot portion having preselected duration is generated on the gate of the regulator transistor in response to the activation of the high current load.
