DS1210S+TRL

Overview

The DS1210S+TRL is a nonvolatile controller chip manufactured by Analog Devices Inc./Maxim Integrated, designed to convert standard CMOS RAM into nonvolatile memory. It operates within a supply voltage range of 4.75V to 5.5V and consumes less than 100nA in battery mode. The component utilizes a 16-pin SO package and supports an operating temperature range of 0°C to +70°C. Key electrical characteristics include a maximum CE propagation delay of 20ns and a typical battery current drain of 100nA.

Feature Summary

Converts CMOS RAM into nonvolatile memory through automatic power-fail detection and battery switching
Unconditionally write-protects data when the incoming supply voltage falls out of tolerance
Supports redundant battery configurations for enhanced reliability and data integrity

Applications

Microprocessor-based systems requiring persistent data storage
Battery-backed real-time clock circuits
Industrial control systems needing reliable nonvolatile memory solutions

Procurement Notes

Verify the specific suffix 'TRL' indicates tape-and-reel packaging rather than tube packaging. Confirm that the commercial temperature grade (0°C to +70°C) meets system requirements, as industrial variants (-40°C to +85°C) exist under different part numbers. Ensure compatibility with the 16-pin SO footprint during procurement planning.

Selection Notes

Select this component when integrating external CMOS SRAM requires nonvolatile capabilities without complex interface logic. Consider the 16-pin SO package for surface-mount applications where space efficiency is prioritized over the 8-pin DIP option. Evaluate the need for redundant battery support if high availability is critical for the target application.

Part Context

The DS1210 series serves as a dedicated nonvolatile controller within the Maxim Integrated portfolio. It addresses the common engineering challenge of maintaining data integrity in volatile memory during power interruptions. The device simplifies system design by integrating power monitoring, write protection, and battery management functions into a single CMOS circuit.
