71M6521DE-IM/F

Overview

The 71M6521DE-IM/F is a single-phase and dual-phase energy meter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features an embedded 16K Flash memory for data storage and configuration. The device is housed in a 68-pin QFN package, designed for high-precision utility metering applications requiring reliable signal processing and long-term data retention capabilities.

Feature Summary

• Supports both single-phase and dual-phase metering configurations
• Integrates non-volatile 16K Flash memory for persistent data storage
• Delivers precision measurement performance suitable for utility-grade applications

Applications

• Single-phase electricity metering systems
• Dual-phase energy monitoring devices
• Smart grid infrastructure components

Procurement Notes

Verify the specific suffix IM/F against official Analog Devices documentation to confirm pinout and thermal pad specifications. Ensure compatibility with existing PCB layouts due to the 68-QFN form factor. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated flash memory within a compact QFN footprint. It is appropriate for applications needing simultaneous support for single and dual-phase topologies without external memory controllers. Evaluate thermal dissipation requirements associated with the QFN package during the design phase.

Part Context

This part belongs to the Maxim Integrated 71M series of energy meter ICs, now under Analog Devices. These components are engineered for accurate power measurement in residential and commercial utility meters. The series emphasizes integration to reduce bill of materials count while maintaining metrological accuracy standards required by regulatory bodies.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering other models from the 71M family or competing manufacturers.
