SELECTABLE INPUT BUFFERS OF GENERAL PURPOSE INPUTS AND MICROCONTROLLERS HAVING THE SAME

One or more embodiments relate, generally, to microcontroller input/output (I/O) and limiting or disabling static current draw at general purpose inputs, including during low power situations where a voltage input may be lower than a supply voltage. In some embodiments, a general purpose input may i...

More Information
Summary:One or more embodiments relate, generally, to microcontroller input/output (I/O) and limiting or disabling static current draw at general purpose inputs, including during low power situations where a voltage input may be lower than a supply voltage. In some embodiments, a general purpose input may include selectable input buffers and logic that is configured to selectively enable an input buffer associated with a voltage domain substantially the same as an input voltage of the general purpose input, and selectively disable the other input buffers.
