MXD1210CSA+

Overview

The MXD1210CSA+ is a nonvolatile RAM controller manufactured by Analog Devices Inc. (formerly Maxim Integrated). It converts standard volatile CMOS RAM into nonvolatile memory using battery backup. The device operates within a supply voltage range of 4.5V to 5.5V and draws 230µA in operating mode. It features write protection during power failures, battery freshness sealing, and optional redundant battery support. The component is housed in an 8-pin SOIC package and supports commercial temperature ranges.

Feature Summary

• Converts standard volatile CMOS RAM into nonvolatile memory
• Provides continuous power supply monitoring for RAM write protection
• Supports battery freshness seal to preserve shelf life during storage
• Enables optional redundant battery selection for extended backup

Applications

• Microprocessor Systems
• Computers
• Embedded Systems

Procurement Notes

Verify the specific suffix 'CSA+' indicates lead-free packaging as per manufacturer ordering guidelines. Confirm that the 8-pin SOIC package matches the design footprint requirements. Ensure the commercial temperature rating aligns with the operational environment specifications before finalizing procurement.

Selection Notes

Select this controller when integrating standard CMOS RAM requires nonvolatile retention capabilities without complex external circuitry. Consider the low quiescent current and compact 8-pin SOIC form factor for space-constrained designs. Evaluate the need for battery redundancy or freshness-seal functionality based on system maintenance requirements.

Part Context

This component belongs to the MXD1210 series of nonvolatile RAM controllers from Analog Devices/Maxim Integrated. The series includes variants with different temperature ratings and package types, such as PDIP and Wide SOIC options. The MXD1210 family is designed to simplify the implementation of battery-backed memory systems in embedded applications.

Replacement Considerations

Direct pin-compatible replacements include other MXD1210 variants like MXD1210ESA+ for extended temperature ranges. Verify electrical characteristics and package dimensions match before substitution.
