DS1284+

Overview

The DS1284+ is a Real-Time Clock (RTC) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides clock and calendar functions with a parallel interface, housed in a 28-DIP package. The device operates on a supply voltage of 4.5V to 5.5V, with battery backup support between 2.4V and 3.5V. It features 50 bytes of SRAM storage and supports time formats of HH:MM:SS:hh in both 12-hour and 24-hour modes. The maximum current consumption during timekeeping is 7mA at 5V. It includes an integrated watchdog timer and square wave output capability.

Feature Summary

Integrated 50-byte SRAM for data storage
Parallel bus interface for microprocessor connection
Built-in watchdog timer and alarm functionality
Supports leap year compensation automatically

Applications

Industrial control systems requiring precise timekeeping
Data logging equipment needing non-volatile memory backup
Embedded systems with parallel bus architectures

Procurement Notes

Verify the specific revision level and RoHS compliance status through official manufacturer documentation before procurement. Confirm availability as distribution channels may vary. Ensure the 28-DIP through-hole package matches the target PCB footprint requirements.

Selection Notes

Select this component when a parallel interface RTC with integrated SRAM and watchdog timer is required. It is suitable for applications operating within the 0°C to +70°C temperature range. Ensure the system design accommodates the 4.5V to 5.5V VCC supply and 2.4V to 3.5V VBAT battery input specifications.

Part Context

The DS1284+ belongs to the Maxim Integrated DS1284/DS1286 family of real-time clocks. These devices are designed to provide accurate timekeeping and date information while maintaining data integrity via battery backup. The '+' suffix typically indicates lead-free and RoHS-compliant manufacturing standards compared to earlier versions.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the DS1286+. Verify functional equivalence regarding SRAM size and feature sets such as the watchdog timer when substituting.
