OVERVIEW
The block diagram in Figure 1 shows the relationships between the major control and memory sections of
the DS2406. The device has four major data components: 64-bit lasered ROM, 1024 bits of EPROM data
memory, status memory, and the PIO-control block. The hierarchical structure of the 1-Wire protocol is
shown in Figure 2. The bus master must first provide one of the five ROM function commands: Read
ROM, Match ROM, Search ROM, Skip ROM, or Conditional Search ROM. The protocol required for
these ROM functions is described in Figure 13. After a ROM functions command is successfully
executed, the PIO-control and memory functions become accessible and the master may provide any one
of the six memory- and control function commands. The protocol for these functions is described in
Figure 7. All data is read and written least significant bit first.
