Abstract:
Certain embodiments of the invention may be found in a method for integrated circuit supporting auto-sense of voltage for drive strength adjustment. The method may comprise detecting an input voltage received at an auto-sense pad integrated on a mobile multimedia processing (MMP) chip. The input voltage may be a power supply voltage of the peripheral device received during power-up of the MMP chip, power-up of the peripheral circuitry, and/or dynamically while the MMP is powered-up. The auto-sense pad may adjust drive strength of at least one other pad, which may be an output pad or a bidirectional pad, integrated on the MMP chip may be configured to operate using the determined output voltage. A rise time and/or fall time of signals output by the MMP chip may be varied by the adjustment of the drive strength.
