71M6513H-IGT/F

Overview

The 71M6513H-IGT/F is a single-phase energy metering System on Chip (SoC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8051-compatible microprocessor core with a maximum clock frequency of 5 MHz, 64 kB of Flash program memory, and 7 kB of data RAM. The device features a 22-bit delta-sigma ADC resolution and supports I2C and UART interfaces. Operating at a supply voltage of 3.3 V, it is housed in a 64-LQFP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates Single Converter Technology with a 22-bit delta-sigma ADC for high-precision measurement
• Combines an 8051-compatible MPU core with flash memory and LCD driver capabilities
• Supports digital temperature compensation via an on-chip temperature sensor

Applications

• Single-phase residential energy metering systems
• Smart grid metering applications requiring isolated sensor integration
• Utility-grade power monitoring devices

Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm hardware revision details, as variations may exist within the 71M65xx family. Confirm availability status through authorized distributors, as older generation components may have limited stock or end-of-life implications. Ensure the LQFP-64 package compatibility matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for single-phase applications requiring integrated metrology and processing. Compare against the 71M6511H for similar performance or the 71M6515H if demo board support is required. Consider the 71M654x series for advanced isolation techniques or higher pin counts. Verify that the 5 MHz clock speed and 64 kB memory suffice for your firmware complexity.

Part Context

This part belongs to the Teridian/Maxim 71M65xx series of metering SoCs, designed to reduce bill-of-materials costs by integrating analog and digital functions. It is often paired with isolated sensor ICs like the 71M6103 to enable shunt-based measurements without costly isolation transformers. The series emphasizes accuracy and tamper immunity for utility applications.

Replacement Considerations

The 71M6511H-IGT/F is a closely related variant within the same family. Check datasheet differences regarding pinout and peripheral availability. No direct cross-manufacturer substitutes are publicly confirmed for this specific legacy part number.
