Abstract

This specification describes an integrated circuit comprising: a single wire interface; a clock circuit configured to detect a voltage from the single wire interface and to generate a clock signal having a frequency that is based on the detected voltage; and a digital system coupled with the single wire interface and the clock circuit. The digital system is configured to: receive a data signal from the single wire interface; power the digital system using a power signal from the single wire interface; and perform one or more operations clocked by the clock signal.

Description

technical field [0001] The present invention relates generally to electronics and more particularly to single wire systems. Background technique [0002] In an example scenario, the system can use a single interface for both data communication and power supply. For example, some 1-wire systems have two pins, one for the 1-wire interface and one for ground. Some 1-wire systems are driven by fixed-value pull-up resistors. In such aspects, system power is limited by design within the limits of the specified resistor values. System design can match this value. [0003] Additionally, in one example scenario, various chips are configured to operate at lower voltages, and the current demand can exceed the amount of current that can be supplied by a simple resistor. To meet the above needs, some systems can be designed to operate in two modes: input / output (I / O) mode and execution mode. During I / O mode, the resistor will power the system. During execute mode, the user will pro...
