Manufacturer Documentation
Technical values were checked against Analog Devices (Maxim Integrated) documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
DS12887 selection and design context
DS12887 is cataloged as a Real-Time Clock in the DS12887 family. Its recorded function is self-contained real-time clock module with integrated battery, crystal and 114 bytes of user RAM. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Timekeeping: Seconds through century with leap-year compensation. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- User RAM: 114 bytes. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Integrated Components: Lithium battery and quartz crystal. Confirm system timing margin and the test conditions attached to the published limit.
- Bus Interface: Parallel microprocessor bus. Confirm logic levels, signaling mode, host support and required external components.
Application and qualification considerations
When evaluating this timing device, confirm oscillator requirements, timekeeping accuracy, backup-supply behavior and serial-interface compatibility. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for DS12887
The recorded package is 24-pin encapsulated DIP module, the temperature range is 0°C to +70°C, and the lifecycle status is Production as of 2026-07-24. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
