DS2415P

Real Time Clock Overview

The DS2415P is a Real-Time Clock (RTC) IC 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, consuming typically 200nA with the oscillator running. It includes a unique, factory-lasered 64-bit registration number for absolute traceability and communicates at 16.3kbits per second. 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 consumption: typically 200nA with oscillator running
• Wide operating voltage range: 2.5V to 5.5V; Temperature range: -40°C to +85°C

Real Time Clock Applications

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

Real Time Clock Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number DS2415P corresponds to the 6-pin TSOC package. Alternative packaging options include Tape & Reel (DS2415P/T&R) or Chip Scale Package (DS2415X). Confirm package type availability with the supplier prior to order placement.

Real Time Clock Selection Notes

Select the DS2415P for applications requiring minimal hardware for timekeeping via a single-wire interface. Ensure an external 32.768kHz quartz crystal is available, as the device requires this component for its on-chip oscillator. Verify that the system supports the 1-Wire protocol commands, including Read ROM, Match ROM, Search ROM, and Skip ROM, before implementation.

Real Time Clock Part Context

The DS2415 belongs to the Maxim Integrated 1-Wire product family. It shares communication requirements with other MicroLAN products due to its built-in multidrop controller. The device uses the same binary time/date representation as the DS2404 but interfaces via the 1-Wire bus instead of parallel interfaces.
