Obsolete status—no longer in production

Device Structure

Single controller IC, nonvolatile RAM type, designed for integration with standard SRAM to provide battery-backed, nonvolatile memory. DIP through-hole package for easy PCB mounting.

Performance Characteristics

Ensures seamless switching from main to backup power for RAM. Low voltage detection for power-fail control. Minimal power consumption during backup operation. Reliable data retention during power interruption.

Application Environments

Widely used in embedded systems, industrial controllers, data loggers, measurement equipment, and any devices requiring nonvolatile memory retention during power failures.

Selection Guidelines

Choose if you need a DIP-packaged, through-hole, nonvolatile RAM controller for 5V logic environments. Confirm the voltage and temperature requirements match your application. Check device’s obsolete status and availability for replacements if designing new products.

Usage Considerations

Carefully design PCB layout for through-hole 8-DIP footprint. Verify supply voltage does not exceed recommended range. Handle as MSL level 1 during assembly. Obsolete component—plan for last-time buy or alternative sourcing.

Potential Equivalent/Replacement Models

This product is obsolete and may be hard to source for long-term production. Potential alternatives include: DS1210 (base part), certain Dallas Semiconductor or Maxim Integrated nonvolatile RAM controllers (such as DS1225, DS1220, DS1230). Equivalent function devices may be available from other manufacturers under different series.
