Real Time Clock datasheet and documents for DS17887-3IND+

DS17887-3IND+

Real Time Clock Overview

The DS17887-3IND+ is a real-time clock (RTC) IC from the DS17x87 series, manufactured by Analog Devices Inc./Maxim Integrated. It integrates a quartz crystal and lithium energy source into a 24-pin encapsulated DIP (EDIP) package. The device provides timekeeping with leap year compensation through 2099, a time-of-day alarm, and 8192 bytes of battery-backed NV SRAM. It operates on a multiplexed byte-wide interface with VCC supply voltages ranging from 2.7V to 3.7V. The industrial temperature range version supports operation from -40°C to +85°C.

Real Time Clock Feature Summary

Integrates a quartz crystal and lithium battery within a 24-pin EDIP package
Provides 8192 bytes of extended battery-backed NV SRAM
Features automatic power-fail detection and switching between primary and backup supplies
Includes a 64-bit silicon serial number and SMI recovery stack

Real Time Clock Applications

Embedded Systems
Utility Meters
Security Systems
Network Hubs, Bridges, and Routers

Real Time Clock Procurement Notes

Verify the specific suffix IND+ indicates the industrial temperature range (-40°C to +85°C). Confirm the EDIP package contains the integrated lithium cell and crystal. Check for RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required voltage range specifications.

Real Time Clock Selection Notes

Select this component when an integrated RTC solution with significant nonvolatile memory is required. The DS17887 variant offers 8KB RAM, compared to 2KB or 4KB in other family members. Verify compatibility with the system's multiplexed bus interface and ensure the 3V operating voltage aligns with the design constraints.

Real Time Clock Part Context

This device belongs to the DS17x87 family, designed as successors to the industry-standard DS12887. Unlike the DS17x85 variants which require external components, the DS17x87 series incorporates the necessary oscillator and power source internally. This integration simplifies PCB layout and reduces component count for embedded applications requiring reliable timekeeping.
