  • Patent number: 5270972
    Abstract: A three-terminal serial-communication peripheral device for low-cost applications is described. The peripheral device comprises a first terminal for receiving a modulated power signal including a source of power and a clocking signal, a second terminal for receiving a reference potential such as a ground reference, and a third terminal for communicating data to and from the peripheral device. The peripheral device further comprises a digital subsystem which exchanges data with an application system. The exchanged data may be stored and retrieved by the digital subsystem, as when the subsystem is a memory unit, or the data may be in the form of measurement data which the peripheral device is supplying to the application system, the measured data being supplied by a sensor of the subsystem. With its three terminals, the peripheral device can communicate data to and from the application system.
