<p>A programmable logic device (405) that includes a voltage input (410) and a detection circuit (440) coupled to the voltage input is described. The detection circuit detects whether a voltage (VPP) applied to the voltage input exceeds a predetermined value. The programmable logic device also includes a configuration circuit (430) coupled to the detection circuit. The configuration circuit configures the programmable logic device to receive a current sufficient for program and erase operations through the voltage input in response to the detection circuit detecting that the voltage exceeds the predetermined value.</p> |
