Maxim Integrated DS2417P

Description
The DS2417 1-Wire Time Chip with Interrupt provides a simple solution for storing and retrieving vital time information with minimal hardware. It 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.

Features
Real-time clock (RTC) with fully compatible 1-Wire MicroLAN interface
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
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
