Key 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 registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures absolute traceability because no two parts are alike
  • 8-bit family code specifies device communication requirements to bus master
  • Built-in multidrop controller ensures compatibility with other MicroLAN products
  • Operates over a wide VDD 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

Applications/Uses

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 micro controller.
