71M6515H-IGT/F

Overview

The 71M6515H-IGT/F is a single-phase energy metering System on Chip (SoC) from the Teridian 71M6x01 series, manufactured by Analog Devices Inc./Maxim Integrated. It integrates a 5MHz 8051-compatible MPU core with Single Converter Technology featuring a 22-bit Delta-Sigma ADC. The device includes digital temperature compensation, a low-power RTC, flash memory, and an LCD driver. It supports residential metering applications with high accuracy over a wide current range.

Feature Summary

• Integrates Single Converter Technology with a 22-bit Delta-Sigma ADC for precise measurement
• Includes a 5MHz 8051-compatible microprocessor core for local processing
• Features digital temperature compensation to maintain accuracy across operating conditions
• Supports direct LCD driving capabilities for user interface display

Applications

• Residential single-phase electricity metering
• Smart grid metering infrastructure
• Utility billing systems requiring ANSI and IEC compliance

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status as per specific manufacturing lot. Check for obsolescence notices or lifecycle changes before finalizing design-in decisions. Ensure supply chain stability given potential discontinuation risks associated with legacy metering SoCs.

Selection Notes

Select this SoC for designs requiring integrated metering and control in a compact footprint. Consider the 64-LQFP package constraints for PCB layout. Evaluate the need for external isolated sensors if magnetic tamper immunity is required. Assess firmware development resources for the 8051 architecture.

Part Context
