DS2415X

Real Time Clock Overview

The DS2415X is a 1-Wire real-time clock and calendar IC in a 6-pin Chip Scale Package. It features a unique 64-bit lasered ROM for identification and a binary counter with 1-second resolution. The device operates on a single data line, communicating at 16.3 kbps. It supports a supply voltage range of 2.5V to 5.5V and functions within an operating temperature range of -40°C to +85°C. Power consumption is typically 200nA with the oscillator active. The RTC accumulates time as seconds since a user-defined reference point.

Real Time Clock Feature Summary

• 1-Wire MicroLAN interface with 64-bit unique lasered ROM
• Binary time/date representation with 1-second resolution
• Clock accuracy of ±2 minutes per month at 25°C
• Low power operation: 200nA typical with oscillator running

Real Time Clock Applications

• Calendar, time, and date stamping for electronic devices
• Logbook functionality in embedded applications
• Stand-alone timekeeping with backup energy source

Real Time Clock Procurement Notes

Verify package type compatibility, as the DS2415X denotes a Chip Scale Package tape and reel configuration. Confirm that the host system supports the 1-Wire protocol and can handle the specific timing requirements for reset and presence pulses. Ensure the external crystal matches the specified load capacitance for accurate timekeeping.

Real Time Clock Selection Notes

Select this component when a compact, low-cost solution for timekeeping is required without complex hardware interfaces. The DS2415X is suitable for systems needing absolute traceability via its unique serial number. Consider the Chip Scale Package dimensions against available PCB space. Verify that the application can provide the necessary pull-up resistor and crystal components for proper bus operation.

Real Time Clock Part Context

The DS2415X belongs to the Maxim Integrated (now Analog Devices) 1-Wire family of time chips. It shares functional similarities with the DS2404 but utilizes the 1-Wire interface instead of parallel connections. The 'X' suffix specifically indicates the Chip Scale Package variant, distinguishing it from the TSOC package versions like the DS2415P.
