DESCRIPTION
The DS2417 1-Wire Time Chip with Interrupt offers a simple solution for storing and retrieving vital
time information with minimal hardware. The DS2417 contains a unique lasered ROM and a real-time
clock/calendar implemented as a binary counter. Only one pin is required for communication with the
device. Utilizing a backup energy source, the data is nonvolatile and allows for stand-alone operation.
The DS2417 features can be used to add functions such as calendar, time and date stamp, and logbook to
any type of electronic device or embedded application that uses a microcontroller.
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 32.768 kHz
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
