MXD1210CSA-T

Overview

The MXD1210CSA-T is a nonvolatile RAM controller in an 8-pin SO package. It converts standard CMOS RAM into nonvolatile memory by monitoring the power supply and providing write protection during marginal conditions. The device switches to battery-backup mode when power fails, ensuring data integrity. Operating voltage ranges from 4.5V to 5.5V. Quiescent current is 230µA in normal mode and 2nA in backup mode. It supports optional redundant batteries and includes a battery freshness seal feature.

Feature Summary

• Battery Backup
• Memory Write Protection
• Battery Freshness Seal
• Optional Redundant Battery

Applications

• Microprocessor Systems
• Computers
• Embedded Systems

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging availability for this part number. Confirm lead-free status if required, as indicated by the '+' symbol in ordering information. Ensure compatibility with the 8-pin SO package dimensions and thermal characteristics specified in the datasheet.

Selection Notes

Select based on required operating temperature range; the 'C' suffix indicates 0°C to +70°C. Consider the TOL pin configuration for power-fail detection thresholds (5% or 10%). Evaluate quiescent current requirements for both normal and battery-backup modes. Verify battery input connections and redundancy options.

Part Context

The MXD1210 series comprises nonvolatile RAM controllers designed to protect volatile CMOS RAM. Variants include PDIP, SO, Wide SO, and CERDIP packages with different temperature ratings. The MXD1210CSA-T belongs to the commercial temperature grade family, offering low-power operation and comprehensive battery management features.

Replacement Considerations

MXD1210CSA+ is a verified lead-free equivalent within the same package and temperature range.
