71M6521FE-IGT/F

Overview

The 71M6521FE-IGT/F is a single-phase residential energy metering System on Chip (SoC) from the Single Converter Technology series. It integrates a high-precision ADC, microcontroller, and memory for utility metering applications. The device operates within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. It features a measurement error of 0.1% and utilizes a 64-LQFP (10x10) surface-mount package.

Feature Summary

• Integrates a complete metering solution with a high-resolution analog-to-digital converter and processing core
• Designed specifically for single-phase residential energy metering applications
• Provides precise power measurement capabilities with low measurement error

Applications

• Single-phase residential electricity meters
• Smart grid metering infrastructure
• Utility billing systems requiring high accuracy

Procurement Notes

Verify component authenticity through Analog Devices or authorized distributors. Confirm that the specific suffix matches the required package and temperature grade. Check current product status as legacy Maxim Integrated products may have limited availability or end-of-life implications. Ensure compatibility with existing PCB footprints for the 64-LQFP package.

Selection Notes

Select this component for single-phase metering designs requiring integrated SoC functionality. Compare against other 71M65xx variants based on specific interface requirements and memory needs. Consider the 64-LQFP package constraints for board layout. Verify that the 3V to 3.6V supply range aligns with the target system power architecture.
