DS2415P/T&R

Real Time Clock Overview

The DS2415P/T&R is a Real-Time Clock (RTC) featuring a fully compatible 1-Wire MicroLAN interface. It utilizes a binary time/date representation with 1-second resolution and achieves clock accuracy of ±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, communicating at 16.3kbits per second. It contains a unique, factory-lasered 64-bit registration number for absolute traceability. Power consumption is typically 200nA with the oscillator running. The component is housed in a compact, low-cost 6-pin TSOC surface mount package.

Real Time Clock Feature Summary

• Real-time clock with 1-Wire MicroLAN interface and 1-second resolution
• Unique 64-bit lasered ROM (8-bit family code + 48-bit serial number + 8-bit CRC)
• Low power operation: 200nA typical with oscillator running
• Wide operating voltage range: 2.5V to 5.5V

Real Time Clock Applications

• Calendar, time, and date stamping for electronic devices
• Logbook functions for embedded applications using microcontrollers
• Stand-alone operation with backup energy source

Real Time Clock Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation. The 'T&R' designation indicates a Tape & Reel packaging format for the DS2415P. Confirm availability status directly with authorized distributors, as supply levels may vary. Ensure the procurement matches the exact part number including the suffix to guarantee correct packaging and handling specifications.

Real Time Clock Selection Notes

Select the DS2415P/T&R when a simple 1-Wire RTC solution is required with minimal hardware overhead. It is suitable for applications needing calendar, time, and date stamping or logbook functions. Ensure the system supports the 1-Wire protocol and can accommodate the external 32.768kHz quartz crystal connection on pins X1 and X2. Verify that the application environment falls within the specified -40°C to +85°C temperature range.

Real Time Clock Part Context

The DS2415P is part of the Maxim Integrated (now Analog Devices) 1-Wire product line. It shares the same binary time/date representation as the DS2404 but offers 1-second resolution. The device integrates a real-time clock counter implemented as a binary counter and a unique lasered ROM. It is designed for multidrop compatibility with other MicroLAN products.
