DS1204V-3

Specialized ICS Overview

The DS1204V-3 is a nonvolatile real-time clock and battery-backed static RAM device manufactured by Analog Devices Inc./Maxim Integrated. It integrates a complete calendar, clock, and watchdog timer with 8 kilobytes of battery-backed static RAM. The component utilizes a parallel interface for data access and operates within a supply voltage range of 2.97 V to 3.63 V. It supports date formats including year, month, day, and day-of-week, alongside 24-hour timekeeping. The device is housed in a DIP-28 package and functions reliably across an operating temperature range from 0°C to +70°C.

Specialized ICS Feature Summary

• Integrates a complete calendar, clock, and watchdog timer with 8 kB of battery-backed static RAM
• Maintains accurate timekeeping and date information during power loss via external battery backup
• Provides parallel bus interface for direct system connection without complex protocol overhead

Specialized ICS Applications

• Industrial control systems requiring persistent time-stamping
• Embedded data logging equipment needing reliable event recording
• Telecommunications infrastructure maintaining synchronized operational logs

Specialized ICS Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and package variants. Ensure compatibility with existing system voltage levels and interface requirements before integration. Confirm availability status through authorized distributors as supply conditions may vary. Validate RoHS compliance and environmental specifications for intended deployment regions.

Specialized ICS Selection Notes

Select this component when a dedicated parallel interface RTC with substantial onboard memory is required. Consider the DIP-28 form factor for through-hole mounting constraints. Evaluate the fixed voltage operation range against system power rails. This part suits applications prioritizing hardware-level timekeeping reliability over software-managed solutions.

Specialized ICS Part Context

The DS1204 series belongs to Maxim Integrated's family of nonvolatile real-time clocks. These devices combine timekeeping functionality with persistent storage capabilities. The DS1204V-3 specifically denotes a variant within this lineage, designed for robust standalone operation in embedded environments where continuous time tracking is critical for system integrity and data accuracy.

Specialized ICS Replacement Considerations

Consult official Analog Devices substitution guides for verified compatible alternatives. Cross-reference pinouts and electrical specifications to ensure functional equivalence. Verify that any substitute maintains the same parallel interface architecture and memory capacity.
