DS2417
1-Wire Time Chip with Interrupt
FEATURES
 Real-time clock (RTC) with fully compatible
1-Wire^® MicroLAN interface
 Uses the same binary time/date representation
as the DS2404 but with 1 second resolution
 Clock accuracy 2 minutes per month
at 25°C
 Programmable interrupt output for system
wakeup
 Communicates at 16.3kbits per second
 Unique, factory-lasered and tested 64-bit reg-
istration number (8-bit family code + 48-bit
serial number + 8-bit CRC tester) assures ab-
solute traceability because no two parts are
alike
 8-bit family code specifies device communi-
cation requirements to bus master
 Built-in multidrop controller ensures com-
patibility with other MicroLAN products
 Operates over a wide V_DD voltage range of
2.5V to 5.5V from -40°C to +85°C
 Low power, 200nA typically with oscillator
running
 Compact, low cost 6-pin TSOC and Flip-Chip
surface mount package

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.
