DS1210SN+T&R

Controllers Overview

The DS1210SN+T&R is a nonvolatile controller chip designed to convert CMOS RAM into nonvolatile memory. It operates within a supply voltage range of 4.5V to 5.5V, depending on the TOL pin configuration. The device consumes less than 100nA in battery mode and supports an industrial temperature range from -40°C to +85°C. Packaged in a 16-pin SOIC format, it features automatic power-fail detection, unconditional write protection, and redundant battery support.

Controllers Feature Summary

• Converts standard CMOS RAM into nonvolatile memory by managing power switching between main supply and backup batteries.
• Automatically inhibits chip enable to unconditionally write protect memory when the incoming supply voltage falls out of tolerance.
• Supports redundant battery configurations with internal isolation switches to ensure data integrity during primary battery failure.

Controllers Applications

• Microprocessor-based systems requiring persistent data storage
• Industrial control units needing reliable battery-backed memory
• Embedded devices with strict power-fail protection requirements

Controllers Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging against official manufacturer documentation. Confirm the 'N' designation for industrial temperature range (-40°C to +85°C) matches system environmental specifications. Ensure compatibility with 16-pin SOIC footprints during PCB layout validation.

Controllers Selection Notes

Select this component when integrating external CMOS SRAM requires nonvolatile capabilities without complex interface logic. Consider the optional power-fail detection thresholds based on TOL pin connections. Evaluate the low battery current consumption for applications prioritizing extended standby life.

Controllers Part Context
