MXD1210CWE

Overview

The MXD1210CWE is a nonvolatile RAM controller manufactured by Analog Devices Inc./Maxim Integrated. It converts standard volatile CMOS RAM into nonvolatile memory and monitors the power supply to provide write protection during marginal conditions. The device switches to battery-backup mode when power fails. It operates within a temperature range of 0°C to +70°C and uses a 16-pin Wide SO package. Supply voltage ranges from 4.5V to 5.5V, with a quiescent current of 230µA in operating mode.

Feature Summary

• Battery backup capability
• Memory write protection
• Battery freshness seal
• Optional redundant battery support

Applications

• Microprocessor Systems
• Computers
• Embedded Systems

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) and 'WE' denotes the 16-pin Wide SO package. Confirm lead-free status if required, as indicated by the '+' symbol in ordering information. Ensure compatibility with standard CMOS RAM interfaces for proper integration.

Selection Notes

Select this component for applications requiring reliable data retention in volatile RAM without complex nonvolatile memory architectures. Consider the low quiescent current and battery redundancy features for systems needing extended battery life and fault tolerance against power failures.

Part Context

The MXD1210 series includes variants like MXD1210EWE for extended temperature ranges (-40°C to +85°C) and MXD1210MJA for military grades. The C suffix specifically designates the commercial grade suitable for general-purpose computing and embedded environments where moderate thermal stability is sufficient.
