DS2417
OVERVIEW
The DS2417 has two main data components: 1) 64-bit lasered ROM, and 2) real-time clock counter
(Figure 1). The real-time clock utilizes an on-chip oscillator that is connected to an external 32.768kHz
crystal. The hierarchical structure of the 1-Wire protocol is shown in Figure 2. The bus master must first
provide one of four ROM function commands: 1) Read ROM, 2) Match ROM, 3) Search ROM, 4) Skip
ROM. The protocol for these ROM functions is described in Figure 7. After a ROM function command
is successfully executed, the real-time clock functions become accessible and the master may then
provide one of the real-time clock function commands. The protocol for these commands is described in
Figure 5. All data is read and written least significant bit first.

Crystal pins. Connections for a standard 32.768kHz quartz crystal, EPSON part
number C-002RX or C-004R (be sure to request 6pF load capacitance).
NOTE: X1 and X2 are very high impedance nodes. It is recommended that they
and the crystal be guard-ringed with ground and that high frequency signals be
kept away from the crystal area. See Figure 10 and Application Note 58 for de-
tails.
