DS2417X/T&R

Real Time Clock Overview

The DS2417X/T&R is a 1-Wire Real-Time Clock (RTC) with interrupt functionality, manufactured by Analog Devices Inc./Maxim Integrated. It features a unique factory-lasered 64-bit registration number for absolute traceability and operates over a wide VDD voltage range of 2.5V to 5.5V from -40°C to +85°C. The device utilizes a binary time/date representation with 1-second resolution and achieves clock accuracy within ±2 minutes per month at 25°C. Communication occurs at 16.3kbits per second via the 1-Wire MicroLAN interface. It includes a programmable interrupt output for system wakeup and consumes low power, typically 200nA with the oscillator running.

Real Time Clock Feature Summary

• 1-Wire MicroLAN interface with unique 64-bit lasered ROM
• Binary RTC counter with 1-second resolution and ±2 min/month accuracy
• Programmable interrupt output for system wakeup
• Low power consumption: 200nA typical with oscillator running

Real Time Clock Applications

• Calendar, time, and date stamping in electronic devices
• Logbook functions for embedded applications
• System wakeup triggers via programmable interrupts

Real Time Clock Procurement Notes

Verify that the 'T&R' suffix indicates Tape & Reel packaging as specified in the ordering information. Confirm the 'X' designation corresponds to the Flip-Chip package variant. Ensure compatibility with the required 32.768kHz external crystal and check for RoHS compliance status if lead-free operation is mandatory.

Real Time Clock Selection Notes

Select this component when a single-wire interface is required for timekeeping in space-constrained designs. The Flip-Chip package offers a compact form factor suitable for surface mount applications. Ensure the host microcontroller supports the 1-Wire protocol and can handle the open-drain bus configuration with appropriate pull-up resistors.

Real Time Clock Part Context

The DS2417 series includes variants such as DS2417P (TSOC package) and DS2417P+ (lead-free TSOC). The DS2417X/T&R specifically denotes the Flip-Chip package version supplied in Tape & Reel format. All variants share the same core RTC and 1-Wire functionality but differ in physical packaging and supply method.

Real Time Clock Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical characteristics against any potential cross-reference components before replacement.
