Hardware system identification circuitry

A method comprising:

• determining, by a system-on-a-chip (SOC), a calibration amount of time to charge a capacitor to a voltage substantially equal to a threshold voltage through a calibration resistor, wherein calibration circuitry of an information handling system includes the calibration resistor and the capacitor, wherein the calibration circuitry is coupled to an identification resistor of the information handling system;
• determining an inventory amount of time to charge the capacitor to the voltage substantially equal to the threshold voltage through a parallel combination of the calibration resistor and the identification resistor;
• and
• determining bit strapping information based on the inventory amount of time and the calibration amount of time, wherein the bit strapping information corresponds to an identification for a component in the information handling system.
