71M6521BE-IGT/F

Overview

The 71M6521BE-IGT/F is a residential energy metering System on Chip (SoC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an analog front-end and digital processing capabilities for single-phase power measurement applications. The device operates within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. It is housed in a 64-LQFP package with dimensions of 10x10 mm. Key electrical specifications include XRAM data memory type and interface capabilities suitable for smart metering systems.

Feature Summary

• Integrated system-on-chip architecture combining analog front-end and digital processing for energy metering
• Designed specifically for single-phase residential energy meter applications
• Supports standard communication interfaces for data retrieval and control

Applications

• Single-phase residential electricity meters
• Smart grid metering infrastructure
• Energy monitoring systems requiring integrated analog-to-digital conversion

Procurement Notes

Verify the specific suffix 'BE' against the official Analog Devices datasheet to confirm pinout, speed grade, or packaging variations. Confirm RoHS compliance status ('+') and lead-free characteristics as per current manufacturing standards. Ensure the 64-LQFP package availability matches project requirements. Cross-reference the manufacturer part number with Analog Devices official channels for accurate ordering information.

Selection Notes

Select this component for single-phase metering designs requiring high integration. Evaluate the 64-LQFP footprint against PCB layout constraints. Consider the 3V to 3.6V supply requirement for power management design. Verify that the integrated ADC resolution and accuracy meet the specific metrology class requirements of the target application.

Part Context

This component belongs to the Maxim Integrated 71M65xx series of energy metering SoCs, now under Analog Devices following the 2021 acquisition. These devices are designed to replace discrete solutions by integrating signal conditioning, ADC, and microcontroller functions into a single chip, reducing bill-of-materials complexity for utility meter manufacturers.

Replacement Considerations

Consult the Analog Devices product selector guide for direct replacements within the 71M65xx family. Verify compatibility with existing firmware if upgrading between variants. Check for any discontinued status updates on the official Analog Devices website.
