71M6543FT-IGTR/F

Overview

The 71M6543FT-IGTR/F is a three-phase energy metering system-on-chip manufactured by Analog Devices Inc./Maxim Integrated. It operates on a 3 V to 3.6 V supply voltage and supports surface mount installation in a 100-pin package. The device functions within an operating temperature range of -40°C to +85°C. It integrates metrology capabilities for accurate energy measurement in three-phase applications.

Feature Summary

• Integrated three-phase energy metering system-on-chip architecture
• Surface mount packaging for automated assembly integration
• Wide industrial operating temperature range capability

Applications

• Three-phase energy metering systems
• Industrial power monitoring equipment
• Utility smart meter infrastructure

Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation, as variations such as FT or F may indicate specific tape-and-reel packaging or lead-free status differences. Confirm current availability status directly with authorized distributors, as this component has been identified as discontinued in certain channels. Ensure compatibility with existing board layouts before procurement.

Selection Notes

Select this component when designing three-phase metering solutions requiring integrated system-on-chip functionality. Consider the 100-pin LQFP package constraints for PCB layout. Evaluate the -40°C to +85°C temperature range against environmental requirements. Compare against similar models like the 71M6513 series if fewer phases or different interface options are needed.
