1 / 15 page DS2417 1-Wire Time Chip with Interrupt www.maxim-ic.com FEATURES Real-time clock (RTC) with fully compatible 1-Wire® MicroLAN interface 1 of 15 020707 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 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 PIN ASSIGNMENT 1 2 3 6 5 4 TSOC 150 mil Top view DS2417 rrd#xx 12 3 65 4 Flip Chip, Top View with Laser Mark, Contacts Not Visible. “rrd” = Revision/Date #xx = Lot Number PIN DESCRIPTION Pin 1 GND Pin 2 1-Wire Pin 3 INT Pin 4 VDD Pin 5 X1 Pin 6 X2 ORDERING INFORMATION DS2417P 6-pin TSOC package DS2417P/T&R TSOC Package, Tape & Reel DS2417P+ 6-pin TSOC Package DS2417P+T&R TSOC Package, Tape & Reel DS2417X Flip-Chip, 10k Tape & Reel + Denotes a lead(Pb)-free/RoHS-compliant 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. |
