71M6521DE-IGT/F

Overview

The 71M6521DE-IGT/F is a highly integrated single-phase and dual-phase energy metering system-on-chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an embedded MPU core, real-time clock (RTC), flash memory, and LCD driver capabilities. Designed for residential metering applications, it supports precise measurement functions within a 64-LQFP package.

Feature Summary

• Integrates an MPU core with RTC and flash memory for standalone operation
• Supports both single-phase and dual-phase metering configurations
• Includes built-in LCD driver functionality for direct display interfacing

Applications

• Residential electricity metering systems
• Single-phase smart grid monitoring
• Dual-phase energy measurement devices

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity levels specified in the official datasheet to maintain reliability during assembly processes.

Selection Notes

Select this SoC when requiring integrated processing, memory, and display driving in a compact form factor. Evaluate compatibility with existing firmware architectures due to the embedded MPU core. Consider thermal management requirements associated with the 64-LQFP package for high-density PCB layouts.

Part Context

Part of the Teridian 71M65xx series, which consolidates metering, control, and communication functions. The Maxim Integrated acquisition by Analog Devices integrates this line into ADI's broader power management and sensing portfolio, ensuring continued support and documentation availability.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications before replacing to ensure functional compatibility in existing designs.
