The microcircuit supports the Search 1-Wire Protocol function, which makes it possible for multiple devices to work on one bus. The code is stored in internal non-volatile memory. Data exchange is performed by the 1-Wire Protocol, which requires a single data pin and the common pin. These RW1990 we use an one, which passed performance than others, the CMOS microcircuit is basically a 64-bit single code electronic . This Protocol determines the conditions of alteration of the state of the bus and the time intervals during the synchronization by means of the interruptions of -pulses of the control device. The and writing of the data are performed by thian bit forward., Weight: 0.0992080179 Pounds, Manufacturer: Ntcpefy
