1. An article for a replaceable printer component, comprising an integrated circuit device that includes:
a device controller;
a single pair of conductors to supply power received from a printer controller to the device controller and to carry signals between the device controller and the printer controller; and
a sensor operatively connected to the device controller to sense a voltage and/or a frequency on one or both of the conductors;
wherein the device controller is to send an indication of a sensed voltage and/or a sensed frequency to the printer controller.
