It keeps time in YY-MM-DD-dd date format and HH:MM:SS (12/24 hr) time format over a parallel interface. Onboard 242 bytes of NVSRAM hold configuration or event data without external memory. The module includes alarm, square wave output, and Y2K compliance. Supply range is 2.7 V to 3.7 V; a separate battery input accepts 2.5 V to 3.7 V for timekeeping when main power drops. Timekeeping current draws 2 mA max at 3 V. The industrial temperature grade (−40°C to 85°C) suits outdoor telecom, factory automation, and engine-bay logging applications. ## Lifecycle and compliance Marked as Active in production. ROHS3 compliant. Sourced through independent distribution — quoted to order against an RFQ with current pricing and availability confirmed at quote time.","metaTitle":"DS1687-3IND+ RTC Clock/Calendar, 242B NVSRAM, -40°C~85°C","metaDescription":"DS1687-3IND+ real-time clock from Analog Devices with parallel interface, 242B NVSRAM, alarm, square wave output.
