Real Time Clock datasheet and documents for DS1687-5IND+

DS1687-5IND+

Real Time Clock Overview

The DS1687-5IND+ is a real-time clock (RTC) IC in a 24-pin EDIP package, operating at +5V with an industrial temperature range of -40°C to +85°C. It integrates the DS1685 chip, a 32.768kHz crystal, and a lithium battery into a self-contained module. The device provides timekeeping through 2099 with leap-year compensation, 242 bytes of battery-backed NV SRAM, and a 64-bit silicon serial number. It supports multiplexed parallel bus interfaces and includes power-control circuitry for system wake-up via alarms or kickstart inputs.

Real Time Clock Feature Summary

Integrated EDIP module containing RTC chip, 32.768kHz crystal, and lithium battery
242 bytes of user-accessible nonvolatile RAM with bank switching
+5V operation with industrial temperature rating (-40°C to +85°C)
Power-on control via date/time alarm or external kickstart input

Real Time Clock Applications

Embedded systems requiring autonomous timekeeping
Utility meters needing long-term data retention
Security systems with wake-up capabilities
Network hubs, bridges, and routers

Real Time Clock Procurement Notes

Verify the IND suffix confirms the -40°C to +85°C industrial temperature grade. Confirm the + suffix indicates lead-free/RoHS compliance. Ensure the EDIP package matches the required footprint. Check specific distributor availability as supply status may vary.

Real Time Clock Selection Notes

Select this part over the DS1685 when an integrated solution with embedded battery and crystal is preferred. The DS1687-5IND+ is specified for +5V logic levels; use the DS1687-3IND+ for +3V applications. Verify that the 24-pin EDIP form factor fits the mechanical constraints of the design.

Real Time Clock Part Context

The DS1687 series serves as a successor to industry-standard DS1285/DS1287 PC clocks. It combines the functionality of the DS1685 chip with passive components in a single encapsulated DIP module. This integration simplifies PCB layout by eliminating external crystal and battery connections while ensuring factory-tested timekeeping reliability.
