Abstract: In one example, an article for a replaceable printer component includes an integrated circuit device having a device controller, a conductor to supply power to the device controller and to carry a signal to and from the device controller, and a sensor operatively connected to the device controller to sense a voltage and/or a frequency on the conductor. The device controller to send an indication of a sensed voltage and/or a sensed frequency to the printer controller.
