DS1486P-120+

Real Time Clock Overview

The DS1486P-120+ is a Real-Time Clock (RTC) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a parallel interface for data access and includes a 128 kB non-volatile SRAM memory block. The device supports calendar and clock functions with alarm capabilities, leap year calculation, and square wave output. It is housed in a 34-PowerCap module package.

Real Time Clock Feature Summary

• Integrates a 128 kB non-volatile SRAM for persistent data storage alongside timekeeping functions.
• Provides a parallel interface for high-speed data access to the RTC and memory registers.
• Includes hardware-based calendar logic with automatic leap year adjustment and alarm functionality.

Real Time Clock Applications

• Industrial monitoring systems requiring precise time stamping
• Data logging equipment needing non-volatile memory retention
• Embedded control units with parallel bus architectures

Real Time Clock Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the official datasheet specifications. Ensure compatibility with existing parallel interface designs before integration. Check for any specific handling requirements related to the PowerCap module form factor during assembly.

Real Time Clock Selection Notes

Select this component when a parallel interface is required for RTC and substantial non-volatile storage. Consider the 34-PowerCap module footprint constraints. Evaluate system power supply stability as the device operates within standard voltage ranges. Compare against serial RTC options if board space or pin count is limited.
