71M6513H-IGTR/F

Overview

The 71M6513H-IGTR/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 21-bit ADC resolution, operates at a supply voltage of 3.3 V, and supports I2C and UART interfaces. Packaged in an LQFP-100 format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a low-power RTC with digital temperature compensation for precise timekeeping
• Includes an LCD driver for direct display interfacing
• Supports Single Converter Technology® with precision voltage reference
• Features a 32-bit computation engine for high-accuracy metering calculations

Applications

• Single-phase residential energy metering systems
• Smart grid prepaid metering applications
• Utility-grade electricity monitoring devices

Procurement Notes

Verify the specific suffix 'H' against official Analog Devices documentation to confirm hardware revision or package variant details. Confirm current availability status as Maxim Integrated products are managed through ADI channels. Ensure compatibility with existing PCB footprints for the LQFP-100 package during design validation.

Selection Notes

Select this component for single-phase metering designs requiring integrated MCU capabilities and LCD driving. Compare ADC resolution and memory size against higher-end models like the 71M654x series if polyphase support or higher precision is required. Verify interface requirements for I2C and UART connectivity before finalizing the bill of materials.

Part Context

This part belongs to the 71M65xx series of metering SoCs from Maxim Integrated, now part of Analog Devices. These devices are designed to reduce bill-of-materials costs by integrating analog front-end and digital processing on a single chip. The 71M6513H variant specifically targets single-phase applications with moderate performance requirements.

Replacement Considerations

Check for pin-compatible alternatives within the 71M651x family. Higher-performance replacements may include the 71M654x series for polyphase needs. Verify software compatibility when migrating between different SoC generations.
