Patent ID: 7836232

Claim:
A single wire communication system comprising: an upper control device generating operation data comprising a start signal, a data signal, an ack signal, and a stop signal; a single wire communication module connected to the upper control device, the single wire communication module receiving the operation data and converting the data signal of the operation data to at least one bit of data bit; and a to-be-controlled chip operating by receiving the data bit from the single wire communication module; wherein the single wire communication module comprises: a filter removing noises added to the operation data; a module driver determining whether driven state or dormant state depending on the operation data; an oscillation circuit generating clocks according to the control of the module driver; a start-stop counter generating a signal confirm signal for determining the start signal or the stop signal; a start-stop recognizer providing an enable signal for maintaining the driven state to the module driver depending on the signal confirm signal; a data processor converting the data signal to generate the data bit; and a power supply supplying power for generating the clocks.
