This RW1990 chips we use imported one, which to be reliable performance than others, CMOS microcircuit is essentially an electronic for carrier of the unique 64-bit digital code. The code is stored in the internal nonvolatile memory. The data exchange is performed by the 1-Wire, which requires one data pin and the common pin. The microcircuit supports the function of the 1-Wire of ROM search, which makes it possible for several devices to operate on one bus. This determines the alteration conditions of the bus and the for time intervals during synchronization by the synchropulses cuts of the control device. Data readout and writing are performed by the junior significant bit forward.
