DS2417P+

Real Time Clock Overview

The DS2417P+ is a Real-Time Clock (RTC) with an interrupt output, featuring a fully compatible 1-Wire MicroLAN interface. It utilizes a binary time/date representation with 1-second resolution and maintains clock accuracy within ±2 minutes per month at 25°C. The device operates over a wide VDD voltage range of 2.5V to 5.5V from -40°C to +85°C. Key electrical parameters include a typical operating current of 200nA with the oscillator running, a maximum data rate of 16.3kbits per second, and a 32-bit binary counter capable of accumulating 136 years of seconds. It includes a unique factory-lasered 64-bit registration number for absolute traceability.

Real Time Clock Feature Summary

• Real-time clock with 1-Wire MicroLAN interface and programmable interrupt output
• Unique 64-bit lasered ROM (8-bit family code + 48-bit serial number + 8-bit CRC)
• Binary time/date representation with 1-second resolution and ±2 min/month accuracy
• Low power consumption: typically 200nA with oscillator running

Real Time Clock Applications

• Electronic devices requiring calendar, time, and date stamping functions
• Embedded applications utilizing microcontrollers for logbook capabilities
• Systems needing stand-alone operation with backup energy source support

Real Time Clock Procurement Notes

Verify package type availability, as the DS2417P+ denotes the 6-pin TSOC package in tube packaging. Alternative tape and reel options exist (DS2417P+T&R). Confirm RoHS compliance status via manufacturer documentation prior to ordering. Ensure supply chain sources provide genuine Analog Devices/Maxim Integrated components to guarantee laser-unique ROM integrity.

Real Time Clock Selection Notes

Select the DS2417P+ when a single-wire RTC solution with interrupt capability is required. Ensure the host system supports 1-Wire protocol commands (Read ROM, Match ROM, Search ROM, Skip ROM). Verify that the application environment stays within the -40°C to +85°C operating temperature range. Consider the need for an external 32.768kHz quartz crystal connected to X1/X2 pins for timekeeping functionality.

Real Time Clock Part Context

The DS2417P+ belongs to the Maxim Integrated 1-Wire product family, designed for minimal hardware overhead in timekeeping applications. It shares the 1-Wire communication standard with other devices like the DS2404 but offers integrated interrupt generation. The 'P+' suffix indicates a lead-free/RoHS-compliant 6-pin TSOC package variant.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the verified source material. Designers should evaluate other 1-Wire RTCs or general-purpose real-time clocks based on interface compatibility and pinout requirements if replacement is necessary.
