Real Time Clock datasheet and documents for DS1685EN-5+

DS1685EN-5+

Real Time Clock Overview

The DS1685EN-5+ is a real-time clock (RTC) IC manufactured by Analog Devices Inc./Maxim Integrated. It operates within a voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The device utilizes a multiplexed bus interface and provides timekeeping with a date format of YY-MM-DD-dd and a 24-hour time format. It includes 242 bytes of battery-backed NV RAM, a 64-bit silicon serial number, and power-control circuitry for system wake-up functions. The component is housed in a TSSOP-24 package.

Real Time Clock Feature Summary

Y2K compliant with leap-year compensation valid through 2099
Includes 242 bytes of user-accessible nonvolatile SRAM
Supports system power-on via date/time alarm or kickstart input
Features a 32kHz square-wave output for power management

Real Time Clock Applications

Embedded systems
Utility meters
Security systems
Network hubs, bridges, and routers

Real Time Clock Procurement Notes

Verify the specific suffix 'EN' corresponds to the industrial temperature grade (-40°C to +85°C) and the '+T&R' indicates tape and reel packaging. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the primary supply voltage requirements align with the 4.5V to 5.5V operational range specified for the '-5' variant.

Real Time Clock Selection Notes

Select this model when an industrial temperature range is required alongside a 5V logic interface. The TSSOP-24 package is suitable for surface-mount applications. Consider the DS1685E-5+ if a commercial temperature range (0°C to +70°C) is sufficient, or the PDIP variant if through-hole mounting is preferred. Verify crystal load capacitance settings (6pF or 12.5pF) match the external oscillator components.

Real Time Clock Part Context

The DS1685EN-5+ belongs to the DS1685/DS1687 family of 3V/5V Real-Time Clocks. It serves as a successor to industry-standard PC clocks like the DS1287, offering enhanced features such as a silicon serial number and auxiliary battery input. The 'EN' designation specifically denotes the industrial temperature grade within the TSSOP package lineup.
