1-Wire Devices

详情

The *-Wire® bus is a simple signaling scheme that performs half-duplex bidirectional communications between a host/main controller and one or more nodes sharing a common data line. Both power and data communications are transmitted over this single *-Wire line. For power delivery, nodes capture charge on an internal capacitor when the line is in a high state and then use this charge for device operation when the line is low during data transmission. This unique communication scheme allows you to add memory, authentication, and mixed-signal functions at any time, easily and efficiently.
