Abstract

Systems, methods, and devices for voltage identification using a pulse-width modulation signal are provided. Such an integrated circuit device may include an input/output (I/O) interface and voltage identification (VID) circuitry. The VID circuitry may be coupled to the input/output interface. The voltage identification circuitry may generate a voltage identification signal that is output on the input/output interface. The voltage identification signal may include a pulsed signal having a particular duty cycle that corresponds to a specified voltage level to enable a voltage regulator that receives the voltage identification signal to provide an input voltage to the integrated circuit device at the specified voltage level.
