Patent ID: 8570067

Claim:
An integrated circuit capable of controlling a communication signal, the integrated circuit comprising: I/O voltage supply power ramp controlled communication buffer logic powered by at least one I/O voltage source, the I/O voltage supply power ramp controlled communication buffer logic including communication controller logic operatively coupled to I/O voltage supply power ramp sensor logic and operative to generate a controller logic output control signal in response to a detected voltage level for each of the at least one I/O voltage source, wherein the I/O voltage supply power ramp controlled communication buffer logic is operative to generate an outgoing communication signal in response to the controller logic output control signal; and wherein the outgoing communication signal is: a predetermined outgoing communication signal when the detected voltage level for each of the at least one I/O voltage source is below a corresponding predetermined voltage level; and is based on at least one core logic output signal when the detected voltage level for each of the at least one I/O voltage source is greater than or equal to the corresponding predetermined voltage level.
