Claim Text:
1. An integrated circuit (IC) device comprising: a microcontroller with an input/output I/O circuitry comprising a plurality of input/output ports, and a plurality of external pins coupled with the microcontroller; wherein the microcontroller comprises an I/O voltage supply comprising switching circuitry which is programmable through said microcontroller, at least one of the input/output ports is selectively connected to at least two different I/O supply voltages via switchable connections controlled by the switching circuitry, and wherein the microcontroller is configured to control the switching circuitry to dynamically and selectively control the switchable connections between the at least one input/output port and the at least two different I/O supply voltages, and wherein at least one of the at least two different I/O supply voltages is provided through one of the external pins and another one of the at least two different I/O supply voltages is an internal supply voltage of the microcontroller.
