915 Generation 10PcsLot Rewritable RFID Contact Memory Key RW1990 Ion for Copy Card Keys Cards

These RW1990 chips we use an one which passed performance than others the CMOS microcircuit is basically a 64-bit single digital code electronic carrier
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
The microcircuit supports the ROM Search 1-Wire Protocol function which makes it possible for multiple devices to work on one bus
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 reading and writing of the data are performed by thian bit forward
